Crystal structure of [5-n-butyl-10-(2,5-di-meth-oxy-phen-yl)-2,3,7,8,13,12,17,18-octa-ethyl-porphyrin-ato]nickel(II).

The asymmetric unit of the title nickel(II) porphyrin, [Ni(C48H60N4O2)], contains one independent mol-ecule. The average Ni-N bond length is 1.917 (13) Å. The mol-ecules are arranged in a closely spaced lattice structure in which neighbouring porphyrins are oriented in inversion-related dimers. The nickel(II) porphyrin is characterized by a significant degree of a ruffled (B 1u ) conformation with small contributions from saddle (B 2u ) and wave (y) [Eg (y)], as determined using normal structural decomposition. Disorder in the 2,5-di--meth-oxy-phenyl substituent was modelled over two positions with a 60% occupancy for the major moiety. One of the ethyl groups is also disordered over two positions and was modelled with the major moiety being present in 51.3% occupancy.

Chemical context

The structural chemistry of porphyrin metal complexes is one of the largest explored areas of coordination chemistry. There are many studies available on metal coordination (Scheidt, 2008 ▸), aspects of macrocycle modification (Chmielewski & Latos-Grazynski, 2005 ▸), supra­molecular chemistry (Beletskaya et al., 2009 ▸) and nonplanar systems (Senge, 2006 ▸). Highly substituted porphyrins (octa-, nano-, deca-, undeca- and dodeca­substitued porphyrins) are of specific inter­est due to the increased nonplanarity which results in the alteration of photophysical properties due to distortions within the macrocyclic ring. Non-planar porphyrins have significantly lower fluorescence yields, larger Stokes shifts and a shorter lifetime of the lowest excited state than planar ones (Röder et al., 2010 ▸). This has resulted in the synthesis and structure of numerous highly substituted porphyrins for biomimetic studies (Senge, 2006 ▸; Senge et al., 2015 ▸).

Structural commentary

The title compound contains one mol­ecule in the asymmetric unit. The β-ethyl groups are either orientated above or below the plane. Ethyl groups on pyrrole rings next to a substituted meso-position alternate, whereas ethyl residues neighbouring an unsubstituted meso-position are orientated in the same direction (Fig. 1 ▸).

The average Ni—N distance is 1.917 (13) Å. The largest deviation occurs at the Ni—N2 bond [1.906 (2) Å], which lies between both substituted meso-positions. These lengths are comparable to those in other similar nickel porphyrins, such as [2,3,7,8,12,13,17,18-octa­ethyl-5-(tri­fluoro­meth­yl)porphyrinato]nickel(II), which has an average Ni—N bond length of 1.925 Å (Suzuki et al., 2014 ▸). The angles between the α carbons (Cα) and the meso carbon (C) can be used to determine structural differences between similar porphyrins and differences within the individual porphyin structure. The Cα—C(but­yl)—Cα angle of 119.12 (2)° is smaller than the Cα—C(H)—Cα angle, and the Cα—C(2,5-di­meth­oxy­phen­yl)—Cα angle at 123.2 (2)° is similar to both Cα—C(H)—Cα angles, 122.1 (3)° (C20) and 124.8 (3)° (C15). The 2,5-di­meth­oxy­phenyl group is tilted at an angle of 75.80 (7)° from the 24-atom least-squares plane of the porphyrin ring.

A conformational analysis was performed using the NSD (normal structural decomposition) method developed by Shelnutt and co-workers (Shelnutt et al., 1998 ▸). The conformation is characterized by a significant degree of ruffled (B 1) with small contributions from saddle (B 2) and wave (y) [E(y)] (Fig. 2 ▸). There are also minor contributions from wave (x), [E(x)] and domed (A 2), which is similar to both highly substituted and other Ni(II) porphyrins (Senge et al., 1992 ▸, 2000 ▸; Senge & Bischoff, 2001 ▸). Contributions are also evident in the A 1 in-plane distortion with smaller contributions from the E(x). The tilt of the pyrrole rings against the 24-atom plane are N1 [24.85 (8)°], N2 [25.22 (8)°], N3 [15.79 (10)°] and N4 [17.58 (8)°], with the highest deviation from the mean plane associated with the pyrrole rings closest to the butyl group at C5. The maximum deviations from the least-squares plane are associated with the meso C atoms. C5 deviates from the least-squares plane by 0.880 (2) Å, whereas C10, C15 and C20 deviate from the plane at 0.551 (2), 0.512 (3) and 0.667 (2) Å, respectively. Table 1 ▸ shows the deviation of all atoms in the 24-atom ring.

Supra­molecular features

The unit cell of the title compound consists of two mol­ecules, each at a distance of 4.949 Å from the 24-atom mean plane of the other. The mol­ecules are arranged in a closely spaced lattice structure in which ethyl groups and butyl groups point towards each other to form a cage-like inversion-related dimer (Fig. 3 ▸). Mol­ecules are orientated in a head-to-tail fashion with an Ni⋯Ni separation of 8.9207 (8) Å. Short contacts between the H atoms of the meth­oxy groups and the N atoms (C111—H⋯N3) are present in the packing structure at a distance of 2.671 (3) Å. Other short contacts were found between the n-butyl group (C51 > C54) with the phenyl meth­oxy unit, specifically between H54A⋯C104, at 2.851 (4) Å, the meth­oxy group (O1 > C111) with the ethyl group (C181 > C182) between O1⋯H18C at 2.552 (4) Å, the meth­oxy group (O2B > C108) with the ethyl group (C21 > C22) between O2B⋯H22A at 2.486 (3) Å and the ethyl group (C121 > C122) with the C15 atom, between C15⋯H12E at 2.833 (3) Å. However, there are no π–π inter­actions or hydrogen bonds evident in the crystal structure.

Database survey

A search of the Cambridge Structural Database (CSD, Version 5.36, update November 2014; Groom & Allen, 2014 ▸) gave six hits for 5,10-disubstituted-2,3,7,8,12,13,17,18-octa­ethyl­porphyrins. Senge et al. (1992 ▸) reported the structure of [2,3,7,8,12,13,17,18-octa­ethyl-5,10-di(2-formyl­vin­yl)porph­yrin­ato]nickel(II), with an average Ni—N bond length of 1.900 Å and similar Ca—Cm(H)—Ca angles (122.85–123.58°) compared to the title compound. We also determined the structure of [5,10-di(n-but­yl)-2,3,7,8,12,13,17,18-octa­ethyl­porphyrinato]nickel(II) with and without deuterated chloro­form (Senge et al., 2000 ▸). This compound exhibits an average Ni—N bond length of 1.900 Å and Ca—Cm—Ca angles similar to the title compound, 119.68–121.23° for substituted meso-positions and 122.58–122.65° for unsubstituted meso-positions. Related structures are those of 2,3,7,8,12,13,17,18-octa­ethyl-5,10-di­phenyl­porphyrin, (2,3,7,8,12,13,17,18-octa­ethyl-5,10-di­phenyl­porphyrinato)nickel(II) and (2,3,7,8,12,13,17,18-octa­ethyl-5,10-di­phenyl­porphyrinato)zinc(II) (Senge & Bischoff, 2001 ▸). The free base derivative shows larger Cα—C—Cα angles compared to the title compound. However, as expected, there is a noticeable difference in the angles involving substituted and unsubstituted meso-positions. The angles between substituted meso-positions are in the range 125–125.93°, and 126.90–127.48° for unsubstituted meso-positions. The Ni(II) derivative exhibits angles that are similar to the title compound, 122.12–122.35° for the substituted meso-positions and 123.42–123.78° for the unsubstituted meso-positions. The average Ni—N bond length of 1.923 Å is comparable to that of the title compound. The zinc derivative of this compound exhibits a larger average metal–nitro­gen bond length of 2.054 Å and wider Cα—C—Cα angles, 124.85–125.95° for the substituted meso-positions and 126.81–127.78° for unsubstituted meso-positions, as to be expected for zinc porphyrins.

Other highly substituted porphyrin structures include 5,15-disubstituted-2,3,7,8,12,13,17,18-octa­ethyl­porphyrins (Senge et al., 2000 ▸; Kobayashi et al., 1998 ▸; Jiang et al., 1996 ▸; Zhu et al., 1992 ▸) and 5,10,15-tris­ubstituted-2,3,7,8,12,13,17,18-octa­ethyl­porphyrins (Kalisch & Senge, 1998 ▸; Senge et al., 2000 ▸; Senge & Bischoff, 2001 ▸).

Synthesis and crystallization

The title compound was prepared as reported previously (Senge et al., 2000 ▸). 1-Bromo-2,5-di­meth­oxy­benzene (1 g, 4.6 mmol) was dissolved in tetra­hydro­furan (5 ml) and cooled to 193 K. The solution was treated dropwise with a solution of lithium in cyclo­hexane (2 M, 2.12 ml, 4.8 mmol). The solution was heated to room temperature and over the course of 1 h added to a solution of (5-butyl-2,3,7,8,12,13,17,18-octa­ethyl­porphyrinato)nickel(II) (100 mg, 0.14 mmol) yielding purple crystals of the title compound (60 mg, 0.08 mmol, 50%). The compound was recrystallized from a solution of 1%vol MeOH in CH2Cl2 layered with hexane to yield single crystals suitable for X-ray diffraction.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The C-bound H atoms were placed in their expected calculated positions and refined using a standard riding model: C—H = 0.95–0.98 Å, with U iso(H) = 1.5U eq(C) for methyl H atoms and 1.2U eq(C) for other H atoms. Disorder in the 2,5-di­meth­oxy­phenyl substituent was modelled over two positions with a 60% occupancy for the major moiety. The ethyl group at C12 was modelled over two positions with the major moiety being present in 51.3% occupancy. Restraints and constraints were used to model the disorder with SHELXL2014 (Sheldrick, 2015b ▸) associated with the 2,5-di­meth­oxy­pheny group at C10 (EADP) and the ethyl group at C12 (SADI and EADP). The EADP command was also used to constrain the n-butyl chain at C5.

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