catena-Poly[[diaqua(2,2′-bipyridine-κ2N,N′)zinc]-μ-2,2′-[1,4-phenylenebis(sulfanediyl)]diacetato-κ2O:O′]

In the polymeric title complex, [Zn(C10H8O4S2)(C10H8N2)(H2O)2]n, the Zn2+ ion lies on a twofold rotation axis and exhibits an octahedral environment, in which it is coordinated by two trans O atoms from two symmetry-related 2,2′-[1,4-phenylenebis(sulfanediyl)]diacetate anions, two N atoms from one 2,2′-bipyridine ligand, and two cis O atoms from water molecules. The dihedral angle between the two pyridine rings is 11.5 (1)°. Adjacent Zn2+ ions are bridged in a monodentate manner by the diacetate anions, forming a chain structure extending parallel to [101], and are further linked into the final three-dimensional structure by O—H...O hydrogen bonds between the coordinating water molecules as donor and the non-coordinating carboxylate O atoms as acceptor atoms.
