Triammonium cyclo-tri-μ-imido-triphosphate monohydrate has been prepared by adding ethanol into a mixture of cyclo-tri-μ-imido-triphosphoric acid and ammonia water. When the triammonium cyclo-tri-μ-imido-triphosphate was heated, release of the water of crystallization was observed and no decomposition of the imidophosphate occurred up to 145°C. The imidophosphate decomposed to produce many kinds of condensed phosphates with or without NH and NH2 groups at a temperature higher than 145°C. The sample finally changed to phosphoric acid and oligophosphates including amino and imino groups.
