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
