Abstract: The title Zn^II complex, [Zn(C₄H₄O₅)(C₆H₆N₄S₂)(H₂O)]·2H₂O, with ligands consisting of an oxydiacetate dianion (ODA), a diaminobithiazole (DABT) molecule and a water molecule, displays a distorted octahedral coordination geometry. The tridentate ODA chelates to the Zn^II in a meridional configuration, with the Zn-O(ether) distance of 2.216 (5) Å, much longer than the Zn-O(carboxyl) distances of 2.051 (5) and 2.071 (5) Å. The overlapped arrangement of parallel DABT ligands, with a separation of 3.509 (9) Å between neighboring DABT rings, suggests - stacking between neighboring molecules.
