Coordination compounds of uranyl nitrate with several amide ligands

Reactions of UO2(NO3)2 with an amide L (L = acetamide, N,N-dimethylacetamide, propanamide, valeramide, benzamide, N-methylurea) in aqueous media resulted in formation of 6 coordination compounds [UO2(L)2(NO3)2], their compositions and structures were determined by elemental analysis, IR-spectroscopy, RFA and X-ray diffraction. The molecular structure and assignment of absorption bands for the obtained compounds are confirmed by quantum-chemical calculations.
