Description
Summary:The title compound, [Zn2V2(C5H6NO7P)2O2(H2O)10]·2H2O, contains a [V2O2(pmida)2]4− dimeric anionic unit [where H4pmida is N-(phosphonomethyl)iminodiacetic acid] lying on a centre of symmetry which is exo-coordinated via the two deprotonated phosphonate groups to two Zn2+ cations, with the coordination environment of Zn completed by five water molecules. The crystal packing is mediated by an extensive network of strong and highly directional O—H...O hydrogen bonds involving the water molecules (coordinated and uncoordinated) and the functional groups of pmida4−, leading to a three-dimensional supramolecular network.
