contrast to the bulky 18-ferrocenyl bipyridineligand 7, the 6-allyl 4 and the 18-allyl 5 bipyridineligands react with Ru(bpy)2Cl2 to give the corresponding ruthenium(II) complexes 9 and 10. In the case of ligand 7, the steric bulk of the two nonaferrocenyl wedges at the 4,4′-position of the bipyridine moiety prevents the conversion of the transoid structure of the ligand to the cisiod structure needed
