title: Diaqua-bis(4-formyl-benzoato-κO)zinc(II).
abstract: The Zn(II) atom in the title compound, [Zn(C(8)H(5)O(3))(2)(H(2)O)(2)], which lies on a twofold rotation axis, is coordinated by two monodentate carboxyl-ate groups and two water mol-ecules in a tetra-hedral geometry; the geometry is distorted towards octa-hedral owing to two long Zn⋯O(carbon-yl) contacts [2.512 (2) Å]. Hydrogen-bonding inter-actions give rise to a three-dimensional network. The formyl group is disordered approximately equally over two positions.
