Abstract

Molecular and crystal structures of a number of organouranium or organothorium complexes of the indenyl ligand have been reported. In these compounds the indenyl rings are sigma-linked to the actinide atom through C atoms of the five-membered-ring portion. In the tetrahedral trisindenyl derivatives, An-C distances suggest a trihapto covalent mode of bonding of the indenyl rings. The title compound is the first ever observed where the uranium(IV) is monohapto sigma-bonded to the indenyl rings and exhibits a regular tetrahedral coordination polyhedron. Its characterisation and structure analysis by single-crystal X-ray diffraction are reported here.
