Abstract: In the asymmetric unit of the crystal structure of the title compound, [Zn(C₃H₂O₄)(C₆H₆N₄S₂)(H₂O)]·H₂O, there are two independent Zn^II complex molecules. Each Zn^II ion assumes a distorted square-pyramidal coordination geometry formed by a diaminobithiazole (DABT) ligand, a malonate dianion and a water molecule. Within the chelating DABT ligand, the two thiazole rings are twisted with respect to each other, with dihedral angles of 3.23 (19) and 2.54 (18)°. O-HO and N-HO hydrogen bonding occurs in the crystal structure.
