	Title	Die Kristallstrukturen des Diphenylphosphinsäureamids, Ph2P(0)NH 2, und seines Cäsiumsalzes [Cs{Ph2P(0)NH}] Crystal Structures of Diphenylphosphinic Acid Amide, Ph-,P(0)NH-, and of its Cesium Salt [Cs{Ph2P(0)NH}]
	Abstract	The crystal structures of the monoclinic form of Ph2P(0)NH2 and of its cesium salt, [Cs{Ph2P(0)NH}l have been determined by X-ray methods. Ph2P(0)N H 2: Space group P2,/c, Z = 16, lattice dimensions (-80°C): a = 2530.2(3), b = 858.9(2), c = 2135.5(3) pm, ß = 110.78(1)°, R , = 0.055. Diphenylphosphinic acid amide forms dimeric molecules via N-H- • O hydrogen bonds, the dimeric units again are associated via hydrogen bonds to form infinite double chains along the crystallographic c axis. [Cs{Ph2P(0)NH}]: Space group Pccn, Z = 8 , lattice dimensions (-83°C): a = 1262.8(1), b = 2632.3(2), c = 769.1(1) pm , R\ = 0.024. The compound is associated via Cs-O and Cs-N contacts along the crystallographic [001] axis forming a tubular arrangement. There are no hydrogen bonds.
