In the title complex, [Cd(2)(C(17)H(14)O(4)S)(2)(C(10)H(8)N(2))(2)], which was hydro-thermally synthesized, the Cd(II) cation is hexa-coordinated in a distorted octa-hedral geometry by two N atoms from a 2,2'-bipyridine ligand and by four O atoms from two different 2-[3-carboxyl-atometh-yl-4-(phenyl-sulfan-yl)phen-yl]propano-ate ligands, forming a cyclic dimetallic complex.
