Abstract

The environment of the CoII ion in the title compound, [Co(SO4)(C6H7N)2(H2O)2]n, exhibits an octahedral configuration with the two 3-methylpyridine ligands lying in cis positions with respect to each other and trans to the two coordinated water molecules. The axial positions are occupied by O atoms of the sulfate ions. Co and S atoms occupy special positions (twofold axis, Wyckoff position 4c). Neighboring CoII ions are covalently connected with each other through the sulfate ions, thus creating infinite polymeric chains that run along the c axis. The water molecules are connected with neighboring sulfate ions through strong O—H⋯O hydrogen bonds. Intramolecular hydrogen bonds parallel to the propagation direction of the chains stabilize the polymeric chains, and intermolecular hydrogen bonds between chains connect neighboring chains with each other, thus leading to polymeric double chains.
