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.
