This paper presents a study of photoelectron spectra of a series of triindenylactinide(IV) complexes containing various sigma-bonded ligands. Studies were performed with both He I and He II ionizing sources. The first data on details of the valence electronic structure have been obtained. It is found that the bonding of the ring ligand in indenyl complexes is similar to that found in corresponding cyclopentadienyl complexes even though there are indications of a greater 5f covalency in the former. Along the series of the studied complexes, differences have been found as far as the nature of the sigma-bonded ligand is concerned. There is evidence, in U(ind)/sub 3/CH/sub 3/, of a tendency toward ionicity, which can account for the observed band shape associated with the 5f/sup -1/ ionization in its spectrum.
