The title compound, [Zn(C7H3NO4)(C6H6N4S2)(H2O)]·4H2O, assumes a distorted octa­hedral coordination geometry around the Zn2+ cation, formed by a diamino­bithia­zole (DABT) mol­ecule, a pyridine-2,6-dicarboxyl­ate anion and a water mol­ecule. The pyridine-2,6-dicarboxyl­ate anion chelates to the ZnII atom with a facial configuration. Within the chelating DABT ligand, the two thia­zole 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.
