Poly[aqua‐μ3‐2,2‐dimethyl­malonato‐zinc(II)]

The title complex, [Zn(C₅H₆O₄)(H₂O)]_n, has a two‐dimensional layer structure. The Zn atoms, in a geometry that is closer to trigonal bipyramidal than square pyramidal, are coordinated by two O atoms of a bidentate dimethyl­malonate ligand, two O atoms of monodentate dimethylmalonate ligands and one O atom from the aqua ligand. The crystal structure is characterized by the intra­layer motif of a hydrogen‐bonded network. Neighboring layers are linked together to build up a three‐dimensional network via van der Waals forces.
