 Title    Synthese, Kristallstruktur und Eigenschaften von 1,1,3,3,3-Pentaamino- l-th io -l A \3 A 5-diphosphaz-2-en (NH2)2P(S)N=P(NH2)3 Synthesis, Crystal Structure, and Properties of 1,1,3,3,3-Pentaam ino-l-thio-l A5,3A5-diphosphaz-2-ene (N H 2)2P(S)N =P(NH 2)3  
 Abstract    (NH2)2P(S)N=P(NH2)3 has been prepared by a two step synthesis. Suitable single crystals were obtained from an acetonitrile solution in a temperature gradient between 60 °C and room temperature. The crystal structure of (NH->)tP(S)N=P(NH->)3 has been determined by single cry­ stal X-ray methods (P2,/c, a = 9 9 8 .2 7 (9)> '= 762.78(8), c = 1007.70(15) pm, ß = 107.340(7)°, Z = 4). In the crystal structure each hydrogen atom is subject to a hydrogen bond. Four N-H -N hydrogen bonding interactions per molecule build up a framework connecting two molecules in eight-membered rings. Each sulfur atom shows six distances N -H -S in the range of weak hydrogen bonding interactions.
