| Abstract: | By reaction of RE(NO3)3· nH2O with benzo-12-C-4 or cyclohexyl-12-C-4 (in molar ratio 1:1) in acetonitrile, six anhydrous complexes, RE(NO3)3·benzo-12-C-4(RE = Pr, Gd,Yb, Lu) and RE(NO3)3·cyclohexyl-12-C-4(RE= La, Lu), were obtained. They were characterized by IR and 1H NMR. The crystal structures of RE(NO3)3·benzo-12-C-4(RE= Gd,Lu) and RE(NO3)3·cyclohexyl-12-C-4(RE = La, Lu) were determined by X-ray diffraction analysis. The electronic structures of Lu(NO3)3·L(L=benzo-12-C-4, cyclohexyl-12-C-4)were studied by INDO method. The results showed that the stability of rare earth complexes of benzo-12-C-4 decreased within Pr, Gd, Yb, Lu series, and complexes of cyclohexyl-12-C-4 were more stable than complexes of benzo-12-C-4. It was found that the ether rings of the ligands occured some deformation when complexed with different rare earth ions. |
