Crystal structure, thermal analysis and IR spectroscopy investigations of N, N‐dimethyl‐1,3‐propanediammonium monohydrogenmonophosphate trihydrate

Abstract

A new organic monohydrogenmonophosphate (C 5 . The structure was solved, using the direct methods and refined against F 2 to a reliability R factor of 0.0257. H HPO .(H O)− . The third hydrogen bond type is responsible for the cohesion between the two-dimensional polyanions. Thus, a framework in a threedimensional way is then created. The thermal decomposition of MPAP shows a large endothermic effect corresponding to the elimination of the water molecules and a set of endotherms which are probably due to the evolution of ammonia from the structure and the decomposition. The title compound was also characterized by IR spectroscopy, the interpretation of the spectra is based on theoretical analyses and literature data.
