Complexes (M=Ni, Pd and Pt; X=Cl and NCS; 1= 2,11-bis(dialkyl- phosphinomethyl)benzophenanthrene; alkyl= cyclohexyl t-butyl; aryl= m-tolyl, p-anisyl and m-CF3-C6H4) have been synthesized.An NMR. study of the t-butyl complexes provides evidence for a fan-like motion of the benzophenanthrene moiety over the plane of the complex.
