Tetraaquabis(N,N-dimethylformamide-κO)zinc(II) bis[(2-{3-[2-(carboxylatomethoxy-κ2O,O′)phenyl]pyrazol-1-yl-κN2}acetato-κO)chloridozincate(II)]

Abstract

The asymmetric unit of the title compound, [Zn(C3H7NO)2(H2O)4][Zn(C13H10N2O5)Cl]2, is composed of a single anion and half a cation. The ZnII atom in the monoanion has a distorted triganol–pyramidal geometry, being coordinated by three O atoms and one N atom from one 2-{3-[2-(carboxylatomethoxy)phenyl]pyrazol-1-yl}acetate ligand and one Cl atom. In the dication, the ZnII atom is located on an inversion center and is coordinated by six O atoms in a slightly distorted octahedral geometry. In the crystal, the ions are linked by O—H...O hydrogen bonds, forming a two-dimensional network lying parallel to the ab plane. There are also C—H...O and C—H...Cl interactions present, which lead to the formation of a three-dimensional structure.
