Two uranium(III) anilido complexes were synthesized, Tp* 2 U(NH-C 6 H 4 - p -terpyridine) ( 2-terpy ) and Tp* 2 U(NH-C 6 H 4 - p -CH 3 ) ( 2-ptol ), where Tp* = hydrotris(3,5-dimethylpyrazolyl)borate, by protonation of Tp* 2 UBn ( 1-Bn; Bn = benzyl) with 4-[2,6-di(pyridin-2-yl)pyridin-4-yl]benzenamine or p -toluidine, respectively. Conversion to the respective uranium(IV) imido species was possible by oxidation and deprotonation, forming Tp* 2 U(N-C 6 H 4 - p -terpyridine) ( 3-terpy ) and Tp* 2 U(N-C 6 H 4 - p -CH 3 ) ( 3-ptol ). These compounds were characterized by multinuclear NMR spectroscopy, IR spectroscopy, electronic absorption spectroscopy, and X-ray crystallography.
