N-substituted ethylcarbamates R2NC(O)OC2H5 (where R = C2H5 or C6H5) and RR′NC(O)OC2H5 (where R = H; R′ = C2H5, C6H5(CH3CH and R = C2H5; R′ = C6H5) uranyl nitrate forms complexes of formula UO2(NO3)2·2Ligand, whereas with the chloride only UO2Cl2·2[C2H5NHC(O)OC2H5] has been isolated. In addition the complexes UO22Cl2·2[CH3)2NC(O)OC2H5] and UO2Cl2·3[CH3NHC(O)OC2H5] are described. From the IR spectra the
使用N-取代的乙基氨基甲酸酯R2NC(O)OC2H5(其中R = C2H5或C6H5)和RR'NC(O)OC2H5(其中R = H; R'= C2H5,C6H5(CH3CH和R = C2H5; R'= C6H5) )硝酸铀酰形成式UO2(NO3)2·2Ligand的配合物,而与氯化物仅分离出UO2Cl2·2 [C2H5NHC(O)OC2H5],此外,配合物UO22Cl2·2 [CH3)2NC(O)OC2H5]描述了UO 2 Cl 2·3 [CH 3 NHC(O)OC 2 H 5]。从红外光谱看,配体似乎通过羰基氧原子配位金属。在硝酸根络合物中,阴离子充当螯合配体,导致在铀酰基的赤道平面内发生六配位。对于固态的1:2氯配合物,建议使用氯桥联的二聚体结构。报道并讨论了该配合物的IR和1H nmr光谱数据。
