Aquabis(2-amino-1,3-thiazole-4-acetato-κ2O,N3)nickel(II)

Abstract

In the crystal structure of the title compound, [Ni(C5H5N2O2S)2(H2O)], the NiII cation is located on a twofold rotation axis and chelated by two 2-amino-1,3-thiazole-4-acetate (ata) anions in the basal coordination plane; a water molecule located on the same twofold rotation axis completes the distorted square-pyramidal coordination geometry. Intermolecular O—H...O and N—H...O hydrogen bonding, as well as π–π stacking between parallel thiazole rings [centroid–centroid distance 3.531 (8) Å], helps to stabilize the crystal structure.
