Crystal structure of a zigzag Co^II coordination polymer: catena-poly[[di-chlorido-bis-(methanol-?O)cobalt(II)]-?-bis-(pyridin-3-ylmeth-yl)sulfane-?²N:N'].

ABSTRACT: Reaction of bis-(pyridin-3-ylmeth-yl)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 Co^II cation lies on a crystallographic inversion centre and the S atom of the L ligand lies on a twofold rotation axis. Each Co^II ion is coordinated by two pyridine N atoms from two bridging L ligands, two O atoms from methanol mol-ecules and two chloride anions, all inversion-related. The complex unit has an elongated octa-hedral geometry, in which N₂O₂ donor atoms occupy the equatorial positions and two chloride anions occupy the axial positions. Each L ligand links two Co^II ions, forming an infinite zigzag chain propagating along the c-axis direction and further stabilized by O-H?Cl hydrogen bonds between the methanol mol-ecules and the chloride anions. Adjacent chains in the structure are connected by inter-molecular C-H?Cl hydrogen bonds, resulting in the formation of a three-dimensional supra-molecular architecture.
