Crystal structure of aqua-tris-(isonicotinamide-κN)bis-(thio-cyanato-κN)cobalt(II) 2.5-hydrate.

Tristan Neumann1, Inke Jess1, Christian Näther1.   

Abstract

The asymmetric unit of the title compound, [Co(NCS)2(C6H6N2O)3(H2O)]·2.5H2O, comprises one CoII cation, three isonicotinamide ligands, two thio-cyanate anions, one aqua ligand and two water solvent mol-ecules in general positions, as well as one water solvent mol-ecule that is located on a twofold rotation axis. The CoII cations are octa-hedrally coordinated by two terminally N-bonded thio-cyanate anions, one water mol-ecule and three isonicotinamide ligands, each coordinating via the pyridine N atom. The discrete complexes are linked by inter-molecular O-H⋯O, N-H⋯O and N-H⋯S hydrogen bonding into a three-dimensional network that contains cavities in which the solvent water mol-ecules are located. The latter are linked by further O-H⋯O hydrogen bonds to the network. There are additional short contacts present in the crystal, indicative of weak C-H⋯S, C-H⋯O and C-H⋯N inter-actions.

Chemical context

The synthesis of new coordination polymers with cooperative magnetic properties is still a major field in coordination chemistry. In this context, compounds that show a slow relaxation of the magnetization, such as, for example, single chain magnets, are of special inter­est because of their potential for future applications (Dhers et al., 2015 ▸; Caneschi et al., 2001 ▸; Liu et al., 2010 ▸). To trigger such behavior, cations of large magnetic anisotropy, such as, for example, MnII, FeII or CoII, must be linked by ligands into chains that can mediate a magnetic exchange. Therefore, we are generally inter­ested in the synthesis and the magnetic properties of Co- and Fe-containing thio- and seleno­cyanate coordination polymers (Werner et al., 2014 ▸, 2015a ▸,b ▸,c ▸; Boeckmann et al., 2012 ▸; Wöhlert et al., 2014 ▸). This also includes the synthesis of discrete complexes with a terminal coordination because such compounds can be transformed into the desired polymeric compounds by thermal decomposition reactions (Näther et al., 2013 ▸). In the course of our investigations, we attempted to prepare Co-containing thio­cyanate coordination compounds with isonicotinamide as ligand and obtained crystals of the title compound, [Co(NCS)2(C6H6N2O)3(H2O)]·2.5H2O. However, this phase could not be prepared as a pure phase. To identify these crystals, a single crystal structure analysis was performed and the results are reported herein.

Structural commentary

The asymmetric unit comprises one cobalt(II) cation, two thio­cyanate anions, three isonicotinamide ligands and three water mol­ecules (one as a ligand and two as solvent mol­ecules) that occupy general positions as well as one water solvent mol­ecule that is located on a twofold rotation axis (Fig. 1 ▸). The CoII cation is coordinated by one water mol­ecule, two terminal N-bonded thio­cyanate anions and three terminal isonicotinamide ligands bonded through the pyridine N atom. The Co—N distances to the negatively charged anionic ligands of 2.0746 (1) and 2.0834 (17) Å are shorter than that to the neutral isonicotinamide ligands [Co—N: 2.1725 (16)–2.2059 (15) Å]. The bond angles around the CoII atom deviate slightly from the ideal values [cis angles: 85.81 (6)–92.60 (7)°; trans angles: 173.17 (7)–177.74 (6)°]. The resulting coordination polyhedron can be described as a slightly distorted octa­hedron (Fig. 1 ▸).

Supra­molecular features

In the crystal structure, four symmetry-related complexes are linked by inter­molecular O—H⋯O hydrogen bonding between the water H atoms of the coordinating water mol­ecules of two complexes and the carbonyl O acceptor atoms of two additional complexes into eight-membered rings that are located on centres of inversion (Fig. 2 ▸). These tetra­mers are further connected by inter­molecular O—H⋯O and N—H⋯O hydrogen bonding between water mol­ecules and amide H atoms, respectively, and the carbonyl as well as water acceptor-O atoms into a three-dimensional network (Fig. 2 ▸). There are additional hydrogen bonds between the amide H atoms and the S atoms of the anionic ligands. The N—H⋯S angles deviate only slightly from 180°. Within this network cavities are formed, in which additional water mol­ecules are embedded. These solvent mol­ecules are linked by (water)O—H⋯O(water) hydrogen bonding into chain-like aggregates that consist of five water mol­ecules each, whereby the aggregates are located on twofold rotation axes. These water aggregates are linked by additional O—H⋯O hydrogen bonds involving the carbonyl O acceptor atoms of the isonicotinamide ligands to the network. Finally, there are several short contacts indicative of weak C—H⋯S, C—H⋯O and C—H⋯N inter­actions. Numerical values of the hydrogen-bonding inter­actions are collated in Table 1 ▸.

Database survey

Some metal compounds based on isonicotinamide ligands and thio­cyanates anions are reported in the Cambridge Structure Database (Version 5.37, last update 2015; Groom et al., 2016 ▸). Two Ni-clathrates, one with 9,10-anthra­quinone and the other with pyrene, in which NiII cations are connected by μ-1,3-bridging thio­cyanate ligands into coordination polymers (Sekiya et al., 2009 ▸) and one very similar cadmium compound with 9,10-di­chloro­anthracene as clathrate mol­ecule (Sekiya & Nishikiori, 2005 ▸). Moreover, one compound comprising a three-dimensional coordination network based on Cd(SCN)2 (Yang et al., 2001 ▸) and a compound built up of Cu–NCS layers are also reported (Đaković et al., 2010 ▸). Very recently we reported two discrete complexes with isonicotinamide as co-ligand, one of which is based on Zn(NCS)2 with the ZnII cation in tetra­hedral coordination (Neumann et al., 2016a ▸) while the other is based on Co(NCS)2 in which the CoII cation is octa­hedrally coordinated (Neumann et al., 2016b ▸).

Synthesis and crystallization

Cobalt thio­cyanate and 4-isonicotinamide were obtained from Alfa Aesar and were used without any further purification. Crystals suitable for single crystal structure analysis were obtained from a mixture of 26.3 mg Co(NCS)2 (0.15 mmol) and 73.3 mg 4-isonicotinamide (0.6 mmol) in demineralized water (1.5 ml) within three days. The title compound could not be prepared as a single phase and was always contaminated with a second crystalline phase which could not be identified so far.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The C—H and N—H hydrogen atoms were positioned in calculated positions with U iso(H) = 1.2U eq(C, N) using a riding model with C—H = 0.95 Å for aromatic and N—H = 0.88 Å for amide H atoms. The water hydrogen atoms were located in a difference map, and their bond lengths were constrained to O—H = 0.84 Å and with U iso(H) = 1.5U eq(O).

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.
