Aqua­(2,2′-diamino-4,4′-bi-1,3-thia­zole-κ(2) N (3),N (3′))(thio­diacetato-κ(3) O,S,O′)nickel(II) monohydrate

In the title compound, [Ni(C(4)H(4)O(4)S)(C(6)H(6)N(4)S(2))(H(2)O)]·H(2)O, the Ni(II) cation assumes a distorted octa­hedral coordination geometry formed by a diamino­bithia­zole (DABT) ligand, a thio­diacetate (TDA) dianion and a coordinated water mol­ecule. The tridentate TDA chelates to the Ni cation in a facial configuration, and both chelating rings display the envelope conformations. The two thia­zole rings of the DABT ligand are twisted with respect to each other, making a dihedral angle of 9.96 (9)°. Extensive O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonding is present in the crystal structure.
