Abstract
Abstract The title compound has been obtained by the reaction of the phosphoraneiminato complex Cl2Sb(NPPh3) with chlorine, followed by partial hydrolysis in acetonitrile. The colourless crystals were characterized by a crystal structure determination. Space group P1̅, Z = 2, structure refinement with 8320 observed unique reflections, R = 0.063 with I > 2σ(I). Lattice dimensions at -70 °C: a = 1245.0(6); b = 1277.7(8), c = 1623.8(9) pm, a = 77.97(2)°, β = 86.52(2)°, γ = 67.07(2)°. The compound consists of Ph3PNH2 + ions, [Sb6O10Cl14]4-ions, in which the central unit is a Sb4O6 skeleton with a double heterocubane-like arrangement with two missing corners, and of in cluded acetonitrile molecules without bonding interactions.
