title: Aqua-(2,2'-diamino-4,4'-bi-1,3-thia-zole-κN,N)(pyridine-2,6-dicarboxyl-ato-κO,N,O)zinc tetra-hydrate.
abstract: The title compound, [Zn(C(7)H(3)NO(4))(C(6)H(6)N(4)S(2))(H(2)O)]·4H(2)O, assumes a distorted octa-hedral coordination geometry around the Zn(2+) cation, formed by a diamino-bithia-zole (DABT) mol-ecule, a pyridine-2,6-dicarboxyl-ate anion and a water mol-ecule. The pyridine-2,6-dicarboxyl-ate anion chelates to the Zn(II) atom with a facial configuration. Within the chelating DABT ligand, the two thia-zole rings are twisted by a dihedral angle of 14.52 (8)° with respect to each other. O-H⋯O and N-H⋯O hydrogen bonds occur in the crystal structure.
