✦ Synopsis

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 is further shown that thc spectroscopic properties which are mainly associated with metal and donor atoms in complexes of this type arc closely related to those of the corresponding square planar complexes of the type trans-mX2(PhzPCH2Ph)2].

The X-ray crystal structures of 2,1l-bis(di-R-phosphinomethyl)benzo[c]phenanthrenes (R = Ph, t -Bu) are reported. Both ligands have the same conformation and the substitution of a Ph by a t -Bu group does not cause significant changes in the tetracyclic aromatic unit which shows the same distortions
