Abstract: In the title Zn^II complex, [Zn(C₂H₄NO₂)₂(C₆H₆N₄S₂)]·2H₂O, the Zn^II ion is coordinated by two glycinate anions and a diaminobithiazole (DABT) molecule in a distorted octahedral geometry. Two thiazole rings of the same DABT are twisted with respect to each other with a dihedral angle of 10.56 (6)°. The glycinate chelates to the Zn^II ion by the amino N and carboxylate O atoms; the chelating five-membered ring displays an envelope configuration. A twofold rotation axis passes through the Zn atom and the mid-point of the C-C bond linking the two thiazole rings.
