Tetraphenylphosphonium Trichloroplumbate(II), PPh 4 PbCl 3 · CH 3 CN PPh 4 PbCl 3 · CH 3 CN was obtained by reaction of PbCl 2 and PPh 4 Cl in acetonitrile. It was also formed along with (PPh 4 ) 2 Se 2 Cl 6 when PbSe was treated with chlorine in the presence of PPh 4 Cl. Its crystal structure was determined by X‐ray diffraction ( R = 0.029 for 4186 reflections). The triclinic crystals contain PbCl 3 – ions that are associated to polymer chains. Each Pb atom has distorted square pyramidal coordination; the pyramids share two opposite basal edges. The chloro bridges are rather asymmetrical.
