【 摘 要 】

Reaction of bis­(pyridin-3-ylmeth­yl)sulfane (L) with cobalt(II) chloride in methanol led to the formation of the title coordination polymer, [CoCl2(C12H12N2S)(CH3OH)2]n, in which the CoII cation lies on a crystallographic inversion centre and the S atom of the L ligand lies on a twofold rotation axis. Each CoII ion is coordinated by two pyridine N atoms from two bridging L ligands, two O atoms from methanol mol­ecules and two chloride anions, all inversion-related. The complex unit has an elongated octa­hedral geometry, in which N2O2 donor atoms occupy the equatorial positions and two chloride anions occupy the axial positions. Each L ligand links two CoII ions, forming an infinite zigzag chain propagating along the c-axis direction and further stabilized by O—H⋯Cl hydrogen bonds between the methanol mol­ecules and the chloride anions. Adjacent chains in the structure are connected by inter­molecular C—H⋯Cl hydrogen bonds, resulting in the formation of a three-dimensional supra­molecular architecture.
