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。本文报道用乙腈和水作溶剂,四价铈与O-phenNO的两种同体配合物的合成:Ce(O-phenNO)(NO_3)_3(OH)·H_2O,Ce(O-phenNO)_4(NO_3)(ClO_4)_3·H_2O(以下分别以Ⅰ、Ⅱ表示),和它们的某些性质。
A great deal of work has been published on the study of the complexes of rare earths with aromatic amines nitrogen oxides. The transition of 1,10-phenanthroline-1-oxide (hereinafter abbreviated as O-phenNO) as a bidentate chelate ligand to many transitions Elements form a stable complex, but only with the rare earth compounds and rare earth nitrate trivalent nitrate complexes. This paper reports the synthesis of two isomeric complexes of tetravalent cerium with O-phenNO using acetonitrile and water as solvent: Ce (O-phenNO) (NO_3) _3 (OH) · H_2O and Ce (O-phenNO) ) (ClO_4) _3 · H_2O (hereinafter referred to as I and II respectively), and some of their properties.
