Abstract
The title complex, [Co2(C8H5NO4S)2(C10H8N2)3(H2O)2]·1.3H2O, was synthesized under hydrothermal conditions. The CoII ion is six-coordinated in a slightly distorted octahedral environment resulting from two carboxylate O atoms of two 2-carboxymethylsulfanyl nicotinate (2-CMSN2−) anions, one water molecule and three N atoms of three 4,4′-bipyridine ligands, with one 4,4′-bipyridine ligand situated on a centre of inversion. Two neighboring CoII ions are linked by two anions, giving a dinuclear [Co2(2-CMSN)2] subunit with a Co⋯Co separation of 6.8600 (3) Å. The dinuclear subunits are joined by bridging 4,4′-bipyridine linkers, generating a three-dimensional network structure. Disordered water molecules are situated in the free space of this network. O—H⋯O hydrogen bonding within and between the subunits enhances the stability of the structure.
