Electronic structure and chemical bonding of the dimer of bis(η5-cyclopentadienyl)ytterbium methyl

The electronic structure, charge distribution, and chemical bonding of the dimer of bis-(η⁵-cyclopentadienyl)ytterbium methyl have been studied by an unrestricted INDO program made applicable for the lanthanoid compounds [1]. The bond order, composition, and the nature of the bridge bonds have been discussed. The existence of weak interaction between two ytterbium atoms was shown.
