The crystal structure of title compound consists of discrete complexes in which the CoII cations are octahedrally coordinated to two terminally N-bonded thiocyanate anions and four 4-methylpyridine coligands and represents a new polymorphic modification of Co(NCS)2(4-methylpyridine)4, which is already reported in the literature.

Abstract
The title compound, [Co(NCS)2(C6H7N)4] or Co(NCS)2(4-methylpyridine)4, was prepared by the reaction of Co(NCS)2 with 4-methylpyridine in water and is isotypic to one of the polymorphs of Ni(NCS)2(4-methylpyridine)4 [Kerr & Williams (1977 ▸). Acta Cryst. B33, 3589–3592 and Soldatov et al. (2004 ▸). Cryst. Growth Des. 4, 1185–1194]. Comparison of the experimental X-ray powder pattern with that calculated from the single-crystal data proves that a pure phase has been obtained. The asymmetric unit consists of one CoII cation, two crystallographically independent thiocyanate anions and four independent 4-methylpyridine ligands, all located in general positions. The CoII cations are sixfold coordinated to two terminally N-bonded thiocyanate anions and four 4-methylpyridine coligands within slightly distorted octahedra. Between the complexes, a number of weak C—H⋯N and C—H⋯S contacts are found. This structure represent a polymorphic modification of Co(NCS)2(4-methylpyridine)4 already reported in the CCD [Harris et al. (2003 ▸). NASA Technical Reports, 211890]. In contrast to this form, the crystal structure of the new polymorph shows a denser packing, indicating that it is thermodynamically stable at least at low temperatures. Thermogravimetric and differential thermoanalysis reveal that the title compound starts to decomposes at about 100°C and that the coligands are removed in separate steps without any sign of a polymorphic transition before decomposition.
1. Chemical context
Polymorphism is a widespread phenomenon and of equal importance in academic and industrial research. It is frequently found in organic compounds but there are also several examples where it is observed in coordination compounds (Moulton & Zaworotko, 2001 ▸; Braga & Grepioni, 2000 ▸; Tao et al., 2012 ▸). This is the case, for example, for coordination compounds based on thiocyanate anions, which we have been interested in for several years. The majority of polymorphic modifications in this class of compounds are observed for discrete complexes with terminally N-bonded ligands (Wöhlert et al., 2013 ▸; Neumann et al., 2018a ▸). In contrast, compounds with a bridging coordination of the anionic ligands typically form isomeric modifications (Mautner et al., 2018 ▸; Neumann et al., 2018b ▸; Böhme et al., 2020 ▸; Jochim et al., 2018 ▸). Within this project, we are especially interested in compounds based on Co(NCS)2 which, because if its high magneticotropy, shows a versatile magnetic behavior (Rams et al., 2017 ▸, 2020 ▸). In the course of these investigations, we became interested in 4-methylpyridine as coligand, with a special focus on Co(NCS)2 compounds.
Several compounds based on Co(NCS)2 have already been reported with this ligand, predominantly discrete complexes with a tetrahedral or an octahedral coordination, with most of them forming clathrates (see Database survey). As part of our synthetic work we have obtained crystals that were characterized by single-crystal X-ray diffraction. This proves that a discrete complex with the composition Co(NCS)2(4-methylpyridine)4 was obtained. Based on these findings, a CSD search was performed, which revealed that the structure of a compound with this composition had already been reported by Solacolu and co-workers and Harris and co-workers [refcodes QQQGKG (Solacolu et al., 1974 ▸) and VERNUC (Harris et al., 2003 ▸)]. The title compound crystallizes differently, which means that we have obtained a new polymorphic modification of this complex.
2. Structural commentary
The title compound, Co(NCS)2(4-methylpyridine)4, is isotypic to Ni(NCS)2(4-methylpyridine)4 already reported in the literature (refcode ICMPNI01; Kerr & Williams, 1977 ▸ and Soldatov et al., 2004 ▸). Its asymmetric unit consists of one CoII cation, two thiocyanate anions and four 4-methylpyridine coligands that are located in general positions (Fig. 1 ▸). The metal cations are sixfold coordinated to two terminally N-bonded thiocyanate anions and four 4-methylpyridine coligands into discrete complexes. Bond lengths and angles are comparable to those in the polymorphic modification already reported in the literature (refcode VERNUC; Harris et al., 2003 ▸) and show that a slightly distorted octahedral coordination is present (Table 1 ▸).

The title compound represents a further polymorph of the modifications that have already been reported in the literature [refcodes QQQGKG (Solacolu et al., 1974 ▸) and VERNUC (Harris et al., 2003 ▸)], but it is noted that some contradictory results have been published. The modification reported by Harris and co-workers crystallizes in the tetragonal space group I41/a with eight formula units in the unit cell and a unit-cell volume of 6329.415 Å3. The form reported by Solacolu and co-workers crystallizes in the space group I41/a but with twelve formula units in the unit cell with a unit-cell volume of 6877.013 Å3. However, in the same paper they also present a p-xylene clathrate crystallizing in the same space space group with a unit-cell volume of 6324.998 Å3, which is very similar to that in the modification reported by Harris et al. It is therefore likely that the two unit-cell volumes were accidentally mixed up and that only one modification of Co(NCS)2(4-methylpyridine)4 is reported. This is further supported by the fact that in the form reported by Solacula et al. with Z = 12, each non-hydrogen atom would need a volume of 16.4 Å3, which seem to be much too low for such a complex. Unfortunately, no atomic coordinates are given for the ansolvate and the solvate reported by Solacula et al. and therefore those crystal structures cannot be compared with that of the form reported by Harris et al.
However, if the volume of each non hydrogen atom in the title compound (20.3 Å3) is compared with that of the modification reported by Harris et al. (22.6 Å3), it is obvious that the title compound is much more densely packed, indicating that this modification represents the thermodynamically stable form, at least at 0 K.
3. Supramolecular features
In the crystal structure of the title compound, the discrete complexes are arranged in columns that propagate along the crystallographic b-axis direction (Fig. 2 ▸). A number of C—H⋯N and C—H⋯S contacts are observed between the complexes, but from the H⋯N and H⋯S distances and the C—H⋯N and C—H⋯S angles (Table 2 ▸) it is unlikely that these are significant interactions.

In contrast, the form reported by Harris et al., exhibits three-dimensional pores (Fig. 3 ▸), which might be responsible for the low density of this modification. Moreover, because most clathrates are isotypic to the form reported by Harris et al., it is possible that these solvates lose their solvent molecules and transform into the ansolvate, presumably without collapse of the overall structure.

4. Database survey
A search of the CSD (version 5.43, last update December 2024; Groom et al., 2016 ▸) using CONQUEST (Bruno et al., 2002 ▸) reveals that ten compounds with Co(NCS)2 and 4-methylpyridine are present in the CSD. This includes two discrete complexes with a tetrahedral coordination and the composition Co(NCS)2(4-methylpyridine)2 and Co(NCS)2(4-methylpyridine)2 p-xylene clathrate (refcodes QQQGKD and QQQGKJ; Solacolu et al., 1974 ▸). There is also one compound reported with the composition Co(NCS)2(4-methylpyridine)2·2p-toluidine clathrate in which the cations are linked into chains (refcode CECDAP; Micu-Semeniuc et al., 1983 ▸).
All remaining compounds consists of discrete complexes with the composition Co(NCS)2(4-methylpyridine)4, [refcodes QQQGKG (Solacolu et al., 1974 ▸) and VERNUC (Harris et al., 2003 ▸)] with some of them crystallizing as clathrates [p-toluidine clathrate (CECCOC; Micu-Semeniuc et al., 1983 ▸), p-xylene clathrate (QQQGKJ; Solacolu et al., 1974 ▸), 4-methylpyridine clathrate (XIHHEB, Harris et al., 2001 ▸, and XIHHEB01, Harris et al., 2003 ▸), nitrobenzene, nitroethane and benzene clathrate (ZZZUXU, ZZZUXY and ZZZUYI; Belitskus et al., 1963 ▸)].
Finally, it is noted that for Ni(NCS)2(4-methylpyridine)4, two different polymorphic modifications have also been reported, including two reports on the form that is isotypic to the title compound [refcodes ICMPNI01 (Kerr & Williams, 1977 ▸) and ICMPNI03 (Soldatov et al., 2004 ▸)] and four reports on the form isotypic to Co(NCS)2(4-methylpyridine)4 [ICMPNI (Andreetti et al., 1972 ▸), ICMPNI02 (Harris et al., 2001 ▸) ICMPNI04 and ICMPNI05 (Soldatov et al., 2004 ▸) and ICMPNI06 (Harris et al., 2003 ▸)].
5. Additional investigations
The experimental X-ray powder pattern of the title compound was compared with that calculated from single-crystal data; this proves that a pure crystalline phase has been obtained (Fig. 4 ▸).
Figure 4.
Experimental (top) and calculated (bottom) X-ray powder patterns of the title compound.
The title compound was also investigated by thermogravimetry and differential thermoanalysis (TG-DTA) measurements. Upon heating, several mass losses are observed, which are accompanied by endothermic events in the DTA curve (Fig. 4 ▸). From the DTG curve, it is obvious that all mass losses are poorly resolved (Fig. 5 ▸). The experimental mass loss of the first and second step is in rough agreement with that calculated for the removal of one 4-methylpyridine ligand in each step (Δm calc. = 17.0%). Upon further heating, the remaining 4-methylpyridine ligands are removed and the Co(NCS)2 formed as an intermediate decomposes.

6. Synthesis and crystallization
Synthesis
Co(NCS)2 (99.9%) and 4-methylpyridine (98%) were purchased from Sigma Aldrich. Single crystals of the title compound suitable for structure determination were obtained by dissolving 0.25 mmol (43.8 mg) of Co(NCS)2 in 7 mL of demineralized water. To this solution, 1.00 mmol (97.3 µl) of 4-methylpyridine were added and the reaction mixture was heated to 413 K for 15 min in a closed vial. Afterwards, it was cooled to 363 K and stored at this temperature overnight, leading to the formation of violet-colored crystals. Larger amounts of a crystalline powder were prepared by stirring 0.50 mmol (87.6 mg) of Co(NCS)2 and 2.00 mmol (194.6 µl) of 4-methylpyridine in 2 mL of demineralized water for 3 d at room-temperature. The violet-colored powder was filtered off and dried in air.
Experimental details
The X-ray powder pattern was measured using a Stoe Transmission Powder Diffraction System (STADI P) equipped with a linear, position-sensitive MYTHEN 1K detector from Stoe & Cie. Thermogravimetry and differential thermoanalysis (TG-DTA) measurements were performed in a dynamic nitrogen atmosphere in Al2O3 crucibles with 8°C min−1 using a STA-PT 1000 thermobalance from Linseis. The TG-DTA instrument was calibrated using standard references materials.
7. Refinement
Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. Hydrogen atoms were positioned with idealized geometry (methyl H atoms allowed to rotate and not to tip) and were refined with U ĩso(H) = 1.2U eq(C) (1.5 for methyl H atoms) using a riding model.

Special details
| 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. |
