Crystal structures and Hirshfeld surface analysis of [κ2-P,N-{(C6H5)2(C5H5N)P}Re(CO)3Br]·2CHCl3 and the product of its reaction with piperidine, [P-{(C6H5)2(C5H5N)P}(C5H11N)Re(CO)3Br].

The coordination of the ligands with respect to the central atom in the complex bromido-tricarbon-yl[diphen-yl(pyridin-2-yl)phosphane-κ2 N,P]rhenium(I) chloro-form disolvate, [ReBr(C17H14NP)(CO)3]·2CHCl3 or [κ2-P,N-{(C6H5)2(C5H5N)P}Re(CO)3Br]·2CHCl3, (I·2CHCl3), is best described as a distorted octa-hedron with three carbonyls in a facial conformation, a bromide atom, and a biting P,N-di-phenyl-pyridyl-phosphine ligand. Hirshfeld surface analysis shows that C-Cl⋯H inter-actions contribute 26%, the distance of these inter-actions are between 2.895 and 3.213 Å. The reaction between I and piperidine (C5H11N) at 313 K in di-chloro-methane leads to the partial decoord-ination of the pyridyl-phosphine ligand, whose pyridyl group is replaced by a piperidine mol-ecule, and the complex bromido-tricarbon-yl[diphen-yl(pyridin-2-yl)phosphane-κP](piperidine-κN)rhenium(I), [ReBr(C5H11N)(C17H14NP)(CO)3] or [P-{(C6H5)2(C5H5N)P}(C5H11N)Re(CO)3Br] (II). The mol-ecule has an intra-molecular N-H⋯N hydrogen bond between the non-coordinated pyridyl nitro-gen atom and the amine hydrogen atom from piperidine with D⋯A = 2.992 (9) Å. Thermogravimetry shows that I·2CHCl3 losses 28% of its mass in a narrow range between 318 and 333 K, which is completely consistent with two solvating chloro-form mol-ecules very weakly bonded to I. The remaining I is stable at least to 573 K. In contrast, II seems to lose solvent and piperidine (12% of mass) between 427 and 463 K, while the additional 33% loss from this last temperature to 573 K corresponds to the release of 2-pyridyl-phosphine. The contribution to the scattering from highly disordered solvent mol-ecules in II was removed with the SQUEEZE routine [Spek (2015 ▸). Acta Cryst. C71, 9-18] in PLATON. The stated crystal data for M r, μ etc. do not take this solvent into account.

Chemical context

Phosphine-type ligands having a second type of atom or coordinating function have been of great inter­est in many areas of chemistry. The existence of a second coordination atom with different properties, coordination capability or trans effect adds possibilities during a catalytic cycle (Guiry & Saunders, 2004 ▸). In particular, much attention has been paid to one of the simplest mol­ecules of this kind, di­phenyl­pyridyl­phosphine P(C6H5)2(C5H5N) (PPh2Py). The mol­ecule is a rigid bidentate ligand (Abram et al., 1999 ▸; Knebel & Angelici, 1973 ▸).

The reaction of the di­phenyl­pyridyl­phosphine ligand with the pan class="Chemical">rhenium dimer (Re(CO)3(OC4H8)Br)2 in chloro­form as solvent leads to the complex P,N-{(C6H5)2(C5H5N)P}Re(CO)3Br]·2CHCl3 (I·2CHCl3). It presents a similar structure to the widely studied [(N,N)Re(CO)3(L)] complexes, which have inter­esting photophysical and photochemical properties (Cannizzo et al., 2008 ▸). Complex I has been shown to be a dual emitter (Pizarro et al., 2015 ▸). It is also inter­esting to note that the PPh2Py ligand can be partially decoordinated by reaction of the complex with a monodentate ligand, like piperidine (C5H11N), leading to the complex [P-{(C6H5)2(C5H5N)P}(C5H11N)Re(CO)3Br] (II).

Structural commentary

The mononuclear ReI complex I with a bidentate P,N (chelating) ligand crystallized from a chloro­form solution in the monoclinic space pan class="Chemical">P21/c. Selected geometrical data are summarized in Table 1 ▸, and the mol­ecular structure of complex I·2CHCl3 is given in Fig. 1 ▸. The coordination environment of the central rhenium atom is defined for phos­phorus and nitro­gen atoms from PPh2Py, a bromide atom in an apical position and three carbonyl carbon atoms in a fac correlation, generating a distorted octa­hedral environment. Additionally, two chloro­form mol­ecules crystallize together with the complex mol­ecule.

Supra­molecular features

In the crystal of I·2CHCl the lattice has two solvating mol­ecules of chloro­form per complex mol­ecule. The cell has a larger volume than for the unsolvated one [2836.7 (15) vs 2119.2 (3) Å3 (Venegas et al., 2011 ▸)] whose geometrical parameters are very similar to those of complex I. In the crystal, the chloro­form solvent mol­ecules are involved in weak C—H⋯Br hydrogen bonds and they link the complex mol­ecules to form layers lying parallel to the bc plane (Fig. 3 ▸ and Table 3 ▸).

Hirshfeld surface analysis of complex I·2CHCl3

In order to visualize and qu­antify the inter­molecular inter­actions in the crystal packing of complex I·2CHCl3, in particular those involving the chloro­form solvent mol­ecules, an Hirshfeld surface analysis was performed and two-dimensional fingerprint plots generated. The Hirshfeld surface analysis (Spackman & Jayatilaka, 2009 ▸) and the associated two-dimensional fingerprint plots (McKinnon et al., 2007 ▸) were performed with CrystalExplorer17 (Turner et al., 2017 ▸). The Hirshfeld surface mapped over d norm = d e + d i, is given in Fig. 5 ▸ a (d e represents the distance from the surface to the nearest nucleus external to the surface, and d i is the distance from the surface to the nearest nucleus inter­nal to the surface). In this d norm view (Fig. 5 ▸ a), blue represents the longest distances while the shortest distances are depicted as red spots (Dalal et al., 2015 ▸).

The two-dimensional fingerprint plot for the whole complex is given in Fig. 5 ▸ b. Apart from the H⋯H inter­molecular contacts that contribute ca 15% the other most relevant inter­molecular inter­actions, as determined from the Hirshfeld surface analysis of complex I·2CHCl3, are shown in Fig. 6 ▸. The Cl⋯H/H⋯Cl, O⋯H/H⋯O and C⋯H/H⋯C inter­actions contribute 26.0, 15.4 and 9.8%, respectively, to the Hirshfeld surface. Some distances for these inter­actions are Cl1⋯H19 = 2.90 Å, H22⋯O2 = 2.69 Å and H21⋯Br1 = 2.66 Å.

Thermogravimetric analysis

Thermogravimetric analyses from 25 to 300°C were performed for both compounds under an N2 flux at a heating rate of 1°C min−1 (see Fig. 7 ▸). Thermogravimetric analysis for compound I·2CHCl3 (Fig. 7 ▸, red line), shows that it loses 28% of its mass in a narrow range, between 45 and 60°C. This mass loss is completely consistent with the two solvating chloro­form mol­ecules detected by the crystal structure analysis. The boiling point of chloro­form, 61°C, is almost identical to the temperature where the mass loss stops, suggesting that the chloro­form mol­ecules are weakly bonded to the pan class="Chemical">rhenium ones in the solid. From 60 to 300°C the remaining matrix is completely stable.

Figure 7

Weight loss for I·2CHCl3 (red line) and II (blue line) between room temperature and 300°C.

Compound II loses 12% of its initial mass between 154 and 190°C (Fig. 7 ▸, blue line). This loss of mass can be associated with the release of the aceto­nitrile and piperidine mol­ecules (14.7%). The relatively high temperature at which decomposition begins compared to the pan class="Chemical">piperidine boiling point, 105°C, suggest that it is strongly bonded to II. From 190 to 300°C, another 33% of mass loss is registered, which can be associated with the release of the PPh2Py (36.6%, b.p.163°C).

Database survey

The di­phenyl­pyridyl­phosphine ligand has been extensively studied and used as a monodentate and bidentate ligand with different metals, including RuII (Ooyama & Sato, 2004 ▸) where the pan class="Chemical">CO2-reducing properties of the complex were studied. Another RuII complex with PPh2Py (Kumar et al., 2011 ▸) has been studied as an inhibitor of DNA-topoisomerases of the filarial parasite S. cervi. ReI–nitro­sil complexes with PPh2Py have been studied structurally and photophysically (Machura & Kruszynski, 2006 ▸).

Piperidine is a ligand that has been widely used with various transition metals. It has been used as a ligand with tungsten and molybdenum to study the cis–trans effect by using larger ligands and increasing the steric hindrance (Darensbourg et al., 2007 ▸).

Synthesis and crystallization

The reagents, (Re(CO)3(OC4H8)Br)2 and pan class="Chemical">(C6H5)2(C5H5N)P were used as provided from supplier (Aldrich), with no purification before use. Seccosolv™ solvents were used without any further purification. Standard Schlenck techniques under argon atmosphere were used for all manipulations.

Synthesis of I. 500 mg of (Re(CO)3(OC4H8)Br)2 (0.590 mmol) were dissolved in 5 ml of chloro­form. 312 mg of diphenyl-2-pyridyl­pan class="Chemical">phosphine (1.18 mmol) was dissolved in 10 ml of chloro­form. The two solutions were mixed, changing from colourless to a translucent yellow after 10 minutes of reaction. The reaction was left to continue for a further 2 h. Addition of 2 ml of pentane to the mixture and standing by one day lead to yellow diffraction-quality crystals of I·2CHCl3 (601 mg, 82.8% yield).

Synthesis of II. The compound was prepared by direct reaction between I and an excess of piperidine (pan class="Chemical">C5H11N) at 313 K in CH2Cl2. 50.0 mg of [P,N-{(C6H5)2(C5H5N)P}Re(CO)3Br] (0.082 mmol) were dissolved in 10 ml of CH2Cl2 giving rise to a yellow solution. Then, 40 µL of piperidine (0.51 mmol) was slowly added. The reaction was allowed to continue for six days with constant agitation at 313 K. After cooling, the reaction mixture was layered with aceto­nitrile. Small orange–yellow diffraction-quality crystals were obtained after one week.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 5 ▸. For both compounds, the hydrogen atoms were positioned geometrically and refined using a riding model: C—H = 0.93-0.97 Å with U iso(H) = 1.2U eq(C). For II, the pan class="Chemical">amine hydrogen atom of the piperidine ring was located in a Fourier-difference map and then subsequently refined with a distant constraint of 0.82 Å. During the last stages of the refinement of II, a region of highly disordered electron density was detected within the crystal structure. As no meaningful model could be achieved, SQUEEZE (Spek, 2015 ▸) was used to model the unresolved electron density resulting from the disordered solvent. 25 electrons per cell suggest, in addition to thermogravimetry, a half aceto­nitrile mol­ecule per complex mol­ecule of II. The contribution of this solvent was not included in the crystal data.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
