The complex [UO 2 (NO 3 ) 2 (TMMA)] (TMMA= N , N , N ′, N ′-tetramethylmalonamide) was structurally characterized by single-crystal X-ray diffraction. The complex consists of two bidentate nitrate ions and one bidentate TMMA ligand coordinated to the UO 2 2+ ion. The complex [UO 2 (THMA) 2 ] 2+ (THMA= N , N , N ′, N ′-tetrahexylmalonamide) was prepared as the BF 4 − salt; this material tended to form

viscous liquids. Uranyl dinitrato-amide complexes with the above monoamides and diamides were synthesized and characterized as UO2(NO3)2 · 2A and UO2(NO3)2 · B. The IR and visible absorption spectra of the plutonium and uranium complexes indicate that they are O-bonded and the nitrate group acts as a bidentate group. The NMR spectra of the uranyl monoamide complexes indicate the existence of restricted
