Synthesis and Crystal Structure of a Cesium-tetraimidophosphate-diamide, Cs5[P(NH)4](NH2)2 = Cs3[P(NH)4] · 2 CsNH2Well crystallized Cesium-tetraimidophosphate-diamide is obtained by the reaction of CsNH2 with P3N5 in autoclaves at 673 K within three days. X-ray single crystal investigations led to the following dataCcca, Z = 4, a = 8.192(5) Å, b = 20.472(5) Å,c = 8.252(3) ÅZ(F2o) ≥3σ(F2o) = 916, Z(Var.) = 32, R/Rw=1 = 0.017/0.021The compound contains the hitherto unknown anion [P(NH)4]3-.
Notes:
Gut kristallisiertes Caesium-tetraimidophosphat-diamid entsteht bei der Umsetzung von CsNH2 mit P3N5 in Autoklaven bei 673 K innerhalb von drei Tagen. Röntgenographische Untersuchungen an Einkristallen der Verbindung ergaben:Ccca, Z = 4, a = 8,192(5) Å, b = 20,472(5) Å,c = 8,252(3) ÅZ(F2o) ≥ 3σ(F2o) = 916, Z(Var.) = 32, R/Rw=1 = 0,017/0,021Die Verbindung enthält das bis dahin unbekannte Anion [P(NH)4]3-.
