title: Bis(2-amino-thia-zole-4-acetato)aquazinc(II).
abstract: In the title compound, [Zn(C(5)H(5)N(2)O(2)S)(2)(H(2)O)], the central Zn atom (2 site symmetry) is five-coordinated by two N and three O atoms [Zn-N = 2.047 (3) Å, Zn-O = 2.099 (2) and 1.974 (4) Å] in a distorted square-pyramidal geometry. Besides one O atom from a water mol-ecule, two 2-amino-thia-zole-4-acetate ligands provide two N and two O atoms as coordinated atoms. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds connect the mol-ecules into an infinite three-dimensional framework.
