Abstrakt: The reaction of (C 5 Me 5 ) 2 AnCl 2 (An = Th, U) with 2.8 or 4 equivalents of LiNMe 2 , respectively, affords (C 5 Me 5 ) 2 An(NMe 2 ) 2 in high yields. In addition to improved syntheses, the solid-state structures, voltammetric data, and UV-visible-NIR spectra for these classic actinide bis(dimethylamido) complexes are presented for the first time.
