A new ethylenediammonium monohydrogen-tetraoxophosphate, [NH3 (CH2) 2NH3] 2+ HPO42- has been hydrotherally synthesized and structurally characterized. The crystal structure of the compound consists of layers built up from [HPO4] 2- tetrahedra alternating with layers of the [NH3 (CH2) 2NH3] 2+ dications. In the inorganic layers, [HPO4] 2-groups link together by hydrogen bonds of O-H-O. The inorganic layers and [NH3 (CH2) 2 NH3] 2+ dications link adjacently, forming a network of hydrogen bonds, N-H-O.
