Abstract: The structure of the title compound, [Cu(C₉H₅O₆)₂(C₃H₅N₃S)₂]·2H₂O, comprises discrete units of the four-coordinate Cu complex linked via hydrogen-bonding interactions of the wtare molecules and the amino and carboxylic acid groups. The complex is trans and lies on an inversion centre. The thiadiazole is bound to the metal via a Cu-N [1.953  (3)  Å] bond, while the acid binds via a carboxylate-O atom [Cu-O 1.971  (2)  Å].
