摘要
The title compound, {Na-2[Zn(C3H2O4)(2)].2H(2)O}(n), is a three-dimensional polymeric complex bridged by malonate dianions. The malonate ligand exhibits versatile coordination modes and links two Zn-II and four Na-I atoms. The Zn atom occupies a special position in an inversion centre and is chelated by two malonate ligands [Zn-O=2.0230 (10) and 2.0875 (11) Angstrom]; two other malonates are involved in monodentate coordination of the Zn atom [Zn-O=2.2789 (12) Angstrom], thus completing its octahedral coordination environment. The Na atom also has a distorted octahedral coordination, formed by four carboxylate O atoms of four malonate ligands [2.4328 (15)-2.5493 (13) Angstrom] and two water molecules [2.3749 (15) and 2.4144 (14) Angstrom].
