Abstract: In the structure of the title compound, [Co(SCN)2(C5H6N2)2(H2O)2], the cobalt cation is surrounded by two water molecules, two thiocyanate anions and two 2-methylpyrazine ligands in a slightly distorted octahedron. The cobalt cation is located on a centre of inversion and all other atoms are located in general positions. For the 2-methylpyrazine ligand, only the N atom which is not adjacent to the methyl group is involved in cobalt coordination. The complexes are connected via O-HN and O-HS hydrogen bonding, forming sheets parallel to (010).
