摘要： 关于稀土与芳乔胺氮氧化物配合物的研究已有大量工作发表,1,10-菲啰啉-1-氧化物(以下简写为O-phenNO)作为一双齿螯合配体能与许多过渡元素形成稳定的配合物,但与稀土化合物仅有其与三价稀土硝酸盐形成配合物的报道.

Abstract: Two solid complexes of cerium(Ⅳ) salts with 1,10-Phenanthrolinc-1-oxide(o-phcnNO) were preparcd and characterized, having the composition of Ce(po-henNO) (NO3)3(OH). H2O and Ce(o-PhenNO)4(NO3)(ClO4)3·H2O. IR spectra indicate that the characteristic frequencies assignable to stretching vibration of Ce-O(o-phenNO)bond in these complexes appear in the region of 385-390cm-1Vci-(NO-phenNO) in the region of 255-260cm-1, VN→o and ON-→o of free ligand shift to lower wave numbers upon complexation, The molar conductance and IR spectra data show that NO3-and CIO4- are not coordinated in Ce(oPhenNO)4 (NO3)(CIO4)3·H2O, and all NO3- are coordinated in Ce(c-PhenNO)(NO3)3 (OH), H2O, The UV spectrum of Ce(o-PhenNO)4(NO3)(CIO4)3. H2O is similar to that of the free ligand. The complexes are less soluble in some organic solvents than the ligand.

Key words: Cerium, 1,10-phenanthroline-l-oxide, Complex
