groups have been explored with uranyl nitrate and some selected lanthanide (La, Sm, and Eu) nitrates. All the synthesized ligands as well as their complexes (1-12) of type UO2(NO3)2L (where, L = L1, L2, and L3 for 1, 2, and 3 respectively) and Ln(NO3)3(H2O)L2 (where, Ln = La, L = L1 for 4, L = L2 for 5, and L = L3 for 6; Ln = Sm, L = L1 for 7, L = L2 for 8, and L = L3 for 9; Ln = Eu, L = L1 for 10, L =
在这项研究中,三个配体C 5 H 4 NOCONRR'的配位化学(其中R,R'= i C 3 H 7(L1); R,R'= i C 4 H 9(L2);和R =用硝酸铀酰和一些选定的镧系元素(La,Sm和Eu)硝酸盐探索了由N-氧化物和羧酰胺基组成的H,R'= t C 4 H 9(L3),所有合成的配体及其配合物(1 - 12)型的UO 2(NO 3)2 L(其中,L = L1,L2,和L3为1,2和3)和Ln(NO 3)3(H 2 O)L 2(其中Ln = La,L = 4的L1 , L = 5的L2 , L 6的L3,Ln = Sm, L = L1代表7, L = L2代表8, L = L3代表9; Ln = Eu,L = L1代表10, L = L2代表11, L = L3代表12)已通过元素分析,光谱法表征分析,例如FTIR,1 H-NMR和电喷雾电离质谱(ESI-MS)。固态L1
