Abstract

Complexes [MX~2~(1)] (M = Ni, Pd and Pt; X=Cl and NCS; 1 = 2,11‐bis(dialkyl‐[or diaryl]phosphinomethyl)benzo[c]phenanthrene; alkyl = cyclohexyl t‐butyl; aryl = m‐tolyl, p‐anisyl and m‐CF~3~ C~6~H~4~) have been synthesized.

An NMR. study of the t‐butyl complexes provides evidence for a “fan‐like” motion of the benzo[c]phenanthrene moiety over the plane of the complex.

## Abstract The five‐coordinate mononuclear complexes [M(CO)~3~(**1**)] (M = Fe, Ru; (**1**) = 2,11‐bis(diphenylphosphinomethyl)benzo[c]phenanthrene) have been prepared and assigned trigonal bipyramidal structures with apical phosphorus atoms from IR. and NMR. data.
