Tetra-aqua-bis-(N,N-dimethyl-formamide-κO)zinc(II) bis-[(2-{3-[2-(carboxyl-ato-meth-oxy-κ(2)O,O')phen-yl]pyrazol-1-yl-κN(2)}acetato-κO)chloridozincate(II)].
The asymmetric unit of the title compound, [Zn(C(3)H(7)NO)(2)(H(2)O)(4)][Zn(C(13)H(10)N(2)O(5))Cl](2), is composed of a single anion and half a cation. The Zn(II) 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-(carboxyl-ato-meth-oxy)phen-yl]pyrazol-1-yl}acetate ligand and one Cl atom. In the dication, the Zn(II) atom is located on an inversion center and is coordinated by six O atoms in a slightly distorted octa-hedral 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 inter-actions present, which lead to the formation of a three-dimensional structure.
