Abstract

The tetrametaphosphimate ring in the title compound, (NH4)4+(PO2NH)4-.4H2O exhibits a chair conformation. The tetrametaphosphimate rings are linked by N-HO bonds forming columns along [100]. These columns are interconnected by O-HO and N-HO hydrogen bonds through water molecules and ammonium ions. All H atoms are involved in hydrogen bonding.
