2-Hydroxypropane-1,3-diammonium bis(phosphonato)zincate(II) hemihydrate

Abstract

In the title compound, (C3H12N2O)[Zn(HPO3)2]·0.5H2O, the inorganic macroanionic chain is built up from ZnO4 tetrahedra and HPO3 pseudo-pyramids sharing vertices. The organic dication shows positional disorder of its central –OH group in a 0.614 (7):0.386 (7) ratio. The components interact by way of O—H...O and N—H...O hydrogen bonds. The Zn atom lies on a crystallographic twofold axis and one C atom, the disordered O atoms of the –OH groups and the water O atom lie on a crystallographic mirror plane.
