Abstract
Tris(diethylamino)benzylphosphonium bromide, [(C2H5)2N]3PCH2C6H5+ Br− · CH3CN (1), has been prepared by the reaction of tris(diethylamino)phosphine with benzylbromide in acetonitrile and its structure determined. The colorless crystals are monoclinic, space group P21/n, Z = 4, a = 954.5(11), b = 2552(3), c = 1017.9(9) pm, β = 92.27(8)°. The lattic contains Br− anions and [(C2H5)2N]3PCH2C6H5+ cations. [(C2H5)2N]3PCH2C6H5]+ Br3− (2) has been obtained by treating compound 1 with equimolar quantities of elemental bromine in acetonitrile solution. The yellow-red crystals of 2 are monoclinic, space group P21/n, Z = 4, a = 1065.1(4), b = 1952.9(2), c = 1201.7(2) pm, β = 98.18(2)°, and comprise [(C2H5)2N]3PCH2C6H5+ cations and linear Br3− anions.
