Abstract

In the crystal structure of the title compound, [Ni(C(5)H(5)N(2)O(2)S)(2)(H(2)O)], the Ni(II) cation is located on a twofold rotation axis and chelated by two 2-amino-1,3-thia-zole-4-acetate (ata) anions in the basal coordination plane; a water mol-ecule located on the same twofold rotation axis completes the distorted square-pyramidal coordination geometry. Inter-molecular O-H⋯O and N-H⋯O hydrogen bonding, as well as π-π stacking between parallel thia-zole rings [centroid-centroid distance 3.531 (8) Å], helps to stabilize the crystal structure.
