Chiral biscyclopentadienylniobium(III) complexes


Bimetallic chiral complexes [(η5-C5H4CHMePh)(η5-C5H5) Nb(CO)ML n ] with ML n =Co(CO)4 and HFe(CO)4 have been prepared and characterized. The lability of the metal-metal bond explains the lack of stereostability of these complexes. The two diastereoisomeric forms of polymetallic chiral complexes [(η5- C5H5CHMePh)(η5-C5H5)Nb(CO)[HFe3(CO)11] have been synthetized, separated and their stereostability has been investigated. All the complexes were characterized by elemental analysis i.r. and1H n.m.r. spectroscopy.
