چکیده
In the title compound, [Cr(C(6)H(7)N(4)S(2))(C(6)H(4)O(7))(H(2)O)]·2H(2)O, the Cr(III) atom is in a distorted octa-hedral environment, coordinated by one water mol-ecule, two N atoms from a protonated diamino-bithia-zole ligand and three O atoms from a citrate(4-) anion. The complex is zwitterionic, with the H atom from the uncoordinated carboxyl-ate group of the citrate anion transferred to one amino group of the diamino-bithia-zole ligand. O-H⋯O and N-H⋯O hydrogen bonds link the complexes into layers including the two uncoordinated water mol-ecules.
