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
## 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.
