Cleavage of P4S3 and P4Se3 cage molecules controlled by transition metal–ligand systems. X-Ray crystal structure of [{MeC(CH2PPh2)3}Rh(P3S3)]˙C6H6

Abstract

The reaction of tetraphosphorus trisulphide and tetraphosphorus triselenide with [RhCl(cod)]₂(cod = cycloocta-1,5-diene) in the presence of triphos [triphos = 1,1,1-tris(diphenylphosphinomethy)ethane]yields the compounds [(triphos)Rh(P₃X₃)]˙C₆H₆, X = S or Se, which have been shown by X-ray analysis to contain the (triphos)Rh moiety replacing a basal P atom in the cage molecule.
