Bis(triphenylphosphine)iminium bromide acetonitrile monosolvate

The title compound, C36H30NP2 +·Br−·C2H3N, crystallized from a CH3CN/OEt2 solution as an acetonitrile solvate. The central P—N—P angle [142.88 (10)°] is significantly larger than in the corresponding chloride and iodide structures

Solvate-free bis­(triphenylphosphine)iminium chloride

The title compound, C36H30NP2 +·Cl−, crystallized in the solvate-free form from a CH3CN/OEt2 solution. The chloride anion and the N atom of the [(Ph3P)2N]+ cation are located on a twofold axis, yielding overall symmetry 2 for the cation. The central P—N—P angle [133.0 (3)°] is at the low end of the range of observed P—N—P angles
