A one-dimensional inorganic–organic hybrid compound:catena-poly[ethylenediammonium [indate(III)-di-μ-hydrogenphosphato(V)-μ-hydroxido] monohydrate]

Abstract

The title compound, (C2H10N2)[In(HPO4)2(OH)]·H2O, was synthesized under hydro­thermal conditions. The structure of this hybrid compound consists of isolated inorganic chains with composition ∞[In(HPO4)4/2(OH)2/2] running along [010]. The coordination of the InIII atom is distorted octa­hedral. The ethyl­enediammonium cation and the disordered water mol­ecule (site-occupation factors = 0.7:0.3) ensure the cohesion of the structure via N—H⋯O and O—H⋯O hydrogen bonds.
