Diaquabis(4-formylbenzoato-κO)zinc(II)

The ZnII atom in the title compound, [Zn(C8H5O3)2(H2O)2], which lies on a twofold rotation axis, is coordinated by two monodentate carboxylate groups and two water molecules in a tetrahedral geometry; the geometry is distorted towards octahedral owing to two long Zn⋯Ocarbonyl contacts [2.512 (2) Å]. Hydrogen-bonding interactions give rise to a three-dimensional network. The formyl group is disordered approximately equally over two positions.
