ALKYLINDENYL ORGANOACTINIDES: SYNTHETIC CHEMISTRY, CHARACTERIZATION AND PHYSICAL PROPERTIES

Article abstract of DOI:10.1016/S0022-328X(00)81187-0

Tris(1-ethylindenyl)actinide chloride and tris(1,4,7-trimethylindenyl)actinide chloride (An = U and Th) have been prepared and characterized by chemical analysis and mass spectrometry.The electronic, infrared, Raman and NMR spectra have been recorded.No major steric hindrance was detected and the alkylindenyl groups appear mainly as pentahapto bonded to the actinide.The spectroscopic measurements are consistent with the single crystal X-ray structure of tris(1,4,7-trimethylindenyl)uranium chloride.The magnetic susceptibility of the uranium compounds has been measured between 2 and 300 K.
