The tetrametaphosphimate ring in the title compound [tetraammonium cyc
lo-tetra-mu-imido-tetraphosphate tetrahydrate, (NH4)(4)(PO2NH)(4) . 4H
(2)O] exhibits a chair conformation. The tetrametaphosphimate rings ar
e Linked by N-H ... O bonds forming columns along [100]. These columns
are interconnected by O-H ... O and N-H ... O hydrogen bonds through
water molecules and ammonium ions. All H atoms are involved in hydroge
n bonding.
