Kristallstruktur und Schwingungsspektrum von Tris-trichlorophosphazeno-carbenium-hexachloroantimont [C(N  PCl3)3]+SbCl6−

Crystal Structure and Vibrational Spectrum of Tris-trichlorophosphazeno-carbenium-hexachloroantimonate C(N?PCl₃)₃]⁺SbCl₆^? C(N?PCl₃)₃]SbCl₆ crystallizes in the space group P1 with the lattice constants a = 903 b = 1046, c = 1307 pm and α = 94.8, β = 88.3, γ = 103.8°. Using X- ray diffraction data, the crystal structure was determined and refined to a residual index of 0.027. The structure consists of octahedral SbCl₆^? ions and C(N?PCl₃)₃]⁺ ions having approximately C_3h symmetry; the atoms C, N, P, and one Cl per PCl₃ group lie approximately in a plane. The i. R. and Raman spectrum was registered and assigned.
