Abstract

At room temperature, phosphorodiamidic acid (HPO2(NH2)2) has a mobile hydrogen, which leads to P-NH 3 + and P-O groups in limiting form. According to the spectroscopic analysis, a limiting (zwitterion) or a medium form (compound with mobile hydrogen) is prominent. This mobile hydrogen leads phosphorodiamidic acid to react with itself giving P-N(H)-P bridges and ammonium. We obtained a major compound ammonium salt of diamido 1, 2 imidodiphosphate which is present as 31P MAS NMR, a crystallographic nonequivalency.
