Aminoguanidinium(1+) dihydrogen phosphate was prepared by crystallization from aqueous solution. On the basis of the results of DSC measurements, X-ray structural analysis was carried out at temperatures of 160, 215 and 293K for three aminoguanidinium(1+) dihydrogen phosphate phases ( Formula Not Shown |Z
