It is shown that the ligand 2,ll-bis(diphenylphosphinomethyl)benzo[c]phenanthrene (1) reacts with nickel(II), palladium(I1) and platinum(l1) substrates giving either exclusively, or predominantly, mononuclear complexes of the type trans-[MXz (l)] in which the organic ligand spans trans-positions. It
=C and proton NMR spectra of several arylpalladium and some arylnickel and arylplatinum complexes have been compared. The Ni(PEt&X and Pd(PEt,),X substituents induce a paramagnetic shift of C,,, (of the phenyl ring) which is much larger than that induced by Pt(PEt,),X. However, there are no signific
