Zusammenfassung
Colourless crystals of (NH4)[Li(NH3)(4)][P(NH2)S-3].NH3 were prepared by the reduction of P4S10 with a solution of lithium in liquid ammonia. The X-ray structure determination shows them to contain the pseudo-tetrahedral amidotrithiophosphate anion [P(NH2)S-3](2-) (point group Cs), which is the hitherto unknown final member of a series of previously characterized amidothiophosphates. The ammonium ...

Colourless crystals of (NH4)[Li(NH3)(4)][P(NH2)S-3].NH3 were prepared by the reduction of P4S10 with a solution of lithium in liquid ammonia. The X-ray structure determination shows them to contain the pseudo-tetrahedral amidotrithiophosphate anion [P(NH2)S-3](2-) (point group Cs), which is the hitherto unknown final member of a series of previously characterized amidothiophosphates. The ammonium ion and the ammonia molecule of solvation form an diamminehydrogen(1+)-ion N2H7+ with a short, nearly linear hydrogen bond of 2.864(3) Angstrom.
