The 1 : 1 complexes of chelating diphosphine, [2-{di(m-tolyl)phosphino}ethyl]diphenylphosphine (pmtpf), with nickel(II), palladium(II) and platinum(II) halides and thiocyanates and 2 : 1 complexes with nickel(II) perchlorates have been prepared. Ligand (pmtpf) forms low-spin square-planar and diamagnetic [M(pmtpf)X2](where X = Cl, Br, I or NCS; M = Ni, Pd or Pt) and [Ni(pmtpf)2]- (ClO4)2 complexes. Complexes of metal carbonyls having the general formula [(pmtpf)M(CO)4] (where M = Cr, Mo or W) have also been synthesized. These complexes have been characterized on the basis of element analysis, electronic, infrared and 1H N.M.R. spectral measurements, magnetic susceptibilities and electrical conductance data. In all cases studied this ligand acts as a chelating ditertiary phosphine.
