Crystal Structure of [NH₃ (CH₂) ₂NH₃] HPO₄ Synthesized under Hydrothermal Condition

Abstract

A new ethylenediammonium monohydrogen-tetraoxophosphate, [NH₃ (CH₂) ₂NH₃] ²⁺ HPO₄^2- 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.
