Synthesis, crystal structure and thermal properties of diaquabis(4-methylpyridine-κ<i>N</i>)bis(thiocyanato-κ<i>N</i>)cobalt(II)
The reaction of Co(NCS)<sub>2</sub> and 4-methyl-pyridine (C<sub>6</sub>H<sub>7</sub>N) in water leads to the formation of light-blue single crystals of the title compound, [Co(NCS)<sub>2</sub>(C<sub>6</sub>H<sub>7</sub>N)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>]. The asymmetric unit consists of one Co<sup>II</sup> cation (site symmetry 1) as well as one thio-cyanate anion, one 4-methyl-pyridine coligand and one water mol-ecule in general positions to generate <i>trans</i>-CoN<sub>4</sub>O<sub>2</sub> octa-hedra. In the crystal, the complexes are linked by O-H⋯S hydrogen bonds into a layered network. Powder X-ray diffraction (PXRD) shows that a pure sample has been obtained. Upon heating, the title compound loses its water mol-ecules and transforms into Co(NCS)<sub>2</sub>(C<sub>6</sub>H<sub>7</sub>N)<sub>2</sub>, which is already reported in the literature.
