Crystal structure of tetra-kis-(isonicotinamide-κN)bis-(thio-cyanato-κN)cobalt(II)-isonicotinamide-ethanol (1/2/1).

The asymmetric unit of the title compound, [Co(NCS)2(C6H6N2O)4]·2C6H6N2O·C2H5OH, comprises one Co(II) cation, two thio-cyanate anions, four coordinating and two solvent isonicotinamide molecules and one ethanol solvent mol-ecule. The Co(II) cations are octa-hedrally coordinated by four N-coordinating isonicotinamide ligands and two terminally N-bonded thio-cyanate anions. These discrete complexes are linked by inter-molecular N-H⋯O and N-H⋯S hydrogen-bonding inter-actions into a three-dimensional network. The two isonicotinamide and the ethanol solvent mol-ecules are embedded in channels of this network and are linked through further N-H⋯O and N-H⋯N hydrogen bonds to the network. The ethanol solvent mol-ecule is disordered over two sets of sites (occupancy ratio 0.6:0.4).

Chemical context

There is an increasing inter­est in compounds showing cooperative magnetic properties, such as ferromagnetism, anti­ferromagnetism and metamagnetism or a slow relaxation of the magnetization, indicative of single-mol­ecule or single-chain magnetism (Gao et al., 2009 ▸; Ma et al., 2009 ▸; Palion-Gazda et al., 2015 ▸; Näther et al., 2013 ▸). In this context we have reported on a number of one-dimensional cobalt(II) thio­cyanate coordination compounds with different N-donor co-ligands that show slow relaxations of the magnetization which in some compounds can be traced back to the behaviour of single-chain magnets (SCM) (Wöhlert et al., 2014 ▸; Werner et al., 2014 ▸, 2015a ▸,b ▸,c ▸,). In the course of our systematic investigation of these materials, we became inter­ested in the monodentate ligand isonicotinamide, which can coordinate with the N atom to the CoII atoms, forming the desired one-dimensional compounds. However, instead of the expected chain compound, a discrete complex with additional solvate mol­ecules of composition [Co(NCS)2(C6H6N2O)4]·2C6H6N2O·C2H5OH was obtained in the current study and characterized by single-crystal X-ray diffraction.

Structural commentary

The asymmetric unit of the title compound consists of one CoII cation, two thio­cyanate ligands, six isonicotinamide mol­ecules (four coordinating, two non-coordinating) and one positionally disordered ethanol solvent mol­ecule. The CoII cation is coordinated by two terminal N-bonded thio­cyanate anions and four N-coordinating isonicotinamide ligands, forming a slightly distorted octa­hedron (Fig. 1 ▸). Bond lengths [Co—N range: 2.074 (3)–2.185 (2) Å] and angles [N—Co—N range: 88.09 (9)–91.91 (10)° for cis and 177.27 (10)–178.32 (11)° for trans angles] are indicative for a slight distortion and are comparable with those in similar coordination compounds with CoII, thio­cyanate anions and N-bound co-ligands.

Supra­molecular features

In the crystal structure of the title compound, neighboring complexes are linked into chains extending along the a axis by inter­molecular N—H⋯O hydrogen-bonding inter­actions (Fig. 2 ▸, Table 1 ▸). These chains are further linked into a three-dimensional network by inter­chain N—H⋯S hydrogen bonding between the thio­cyanate anions and the amide H atoms of neighboring complexes (Fig. 3 ▸, Table 1 ▸). In this way, two types of channels are formed along the a axis. In the larger channels, the isonicotinamide solvent mol­ecules are embedded whereas the smaller channels are occupied by the disordered ethanol mol­ecules (Figs. 2 ▸ and 3 ▸). The solvent mol­ecules are linked by O—H⋯O, N—H⋯O and N—H⋯N hydrogen-bonding inter­actions to the the isonicotinamide ligands that form the channels. Weak C—H⋯O and C—H⋯S inter­actions are also observed, consolidating the packing of the crystal structure.

Database survey

In the Cambridge Structure Database (Version 5.37, last update 2015; Groom et al., 2016 ▸) only five structures of coordination compounds with isonicotinamide and thio­cyanate as ligands are reported: two clathrates of nickel coordination polymers, in which the metal atoms are connected into chains by μ-1,3-bridging thio­cyanate ligands of which one contains 9,10-anthra­quinone and the other pyrene as clathrate mol­ecules (Sekiya et al., 2009 ▸). Furthermore, a one-dimensional cadmium 9,10-di­chloro­anthracene-clathrate with bridging μ-1,3-thio­cyanate ligands between the metal atoms is reported (Sekiya & Nishikiori, 2005 ▸), as well as a three-dimensional network consisting of cadmium cations with μ-1,3-bridging thio­cyanate ligands (Yang et al., 2001 ▸), and finally one Cu coordination polymer in which Cu–NCS sheets are observed (Đaković et al., 2010 ▸). In this context we have reported recently on a Zn complex in which the Zn cations are tetra­hedrally coordinated by two terminal N-bonded thio­cyanate anions and two isonicotinamide ligands (Neumann et al., 2016 ▸).

Synthesis and crystallization

Cobalt(II) thio­cyanate and isonicotinamide were obtained from Alfa Aesar and were used without further purification. Single crystals suitable for structure analysis were obtained by the reaction of 26.3 mg Co(NCS)2 (0.15 mmol) with 73.3 mg isonicotinamide (0.6 mmol) in ethanol (1.5 ml) after being allowed to stand for a few days at room temperature.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The C—H, O—H and N—H hydrogen atoms were located in a difference map but were positioned with idealized geometry (methyl and O—H hydrogen atoms were allowed to rotate but not to tip) and were refined with U iso(H) = 1.2U eq(C,N) (1.5 for methyl and O—H hydrogen atoms) using a riding model with C—H = 0.95 Å for aromatic, C—H = 0.98 Å for methyl, N—H = 0.88 Å and O— H = 0.84 Å, respectively. The ethanol mol­ecule was found to be disordered over two sets of sites and was refined with fixed occupation factors of 0.6 and 0.4, respectively.

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.
