title: Decaaqua-dioxidobis[μ(3)-N-(phospho-n-atometh-yl)imino-diacetato]-dizinc(II)-divanadium(IV) dihydrate.
abstract: The title compound, [Zn(2)V(2)(C(5)H(6)NO(7)P)(2)O(2)(H(2)O)(10)]·2H(2)O, contains a [V(2)O(2)(pmida)(2)](4-) dimeric anionic unit [where H(4)pmida is N-(phosphono-meth-yl)imino-diacetic acid] lying on a centre of symmetry which is exo-coordinated via the two deprotonated phospho-nate groups to two Zn(2+) cations, with the coordination environment of Zn completed by five water mol-ecules. The crystal packing is mediated by an extensive network of strong and highly directional O-H⋯O hydrogen bonds involving the water mol-ecules (coordinated and uncoordinated) and the functional groups of pmida(4-), leading to a three-dimensional supra-molecular network.
