Abstract
Abstract Triphenylphosphazenium chloride has been prepared by the reaction of triphenylphosphine with trimethylsilylazide in impure, wet dichloromethane. Yields are improved as stoichiometric quantities of water are added. Colourless crystals are obtained by recrystallization from the same solvent. The crystals are triclinic, space group P1̅, Z=2, a = 894,6(3), b - 979,8(3), c = 1142,9(4) pm, α = 107,27(3), β = 93,70(3), y = 92,97(3)°. In the solid state the compound exists as [(C6H5)3PNH2]+ cations, and Cl- anions. Dimeric units are formed by H-bonding. The crystal structure contains one molecule CH2Cl2 per one molecule (C6H5)3PNH2Cl. The cation has a slightly irregular tetrahedral geometry around the P-atom with a relatively short P-N bond
