N,N′-二甲基-N,N′-二苯基-3-氧杂戊二酰胺及其稀土硝酸盐配合物的合成及表征

Synthesis and Characterization of Complexes of Lanthanide Chlorides With N,N ' -Dimethyl- N,N' -Diphenyl-3-Oxapentanediamide

在非水介质中合成了六种轻稀土硝酸盐与配体Ｎ,Ｎ－二甲基－Ｎ,Ｎ－二苯基－３－氧杂戊二酰胺(ＤＭＤＯ)的固体配合物,通式为 [Ｌｎ(ＤＭＤＯ)(ＮＯ３)３ｌｎＨ２Ｏ(Ｌｎ＝Ｌａ－Ｅｕ,不包括Ｐｍ,ｎ＝０,１,２)。用元素分析、电导、红外光谱、ＩＨ ＮＭＲ和ＴＧ－ＤＴＡ分析对这些配合物进行了表征．结果表明,在这些新配合物中,配体ＤＭＤＯ表现为三齿配位行为．

Abstract: The lighter lanthanide nitrate complexes with the ligand N, N' -dimethyl N, N ' -diphenyl-3-oxapentanediamide (DMDO) have been prepared in non-aqueous media. These complexes with generalformula [Ln (DMDO)(N O3)3]. nH2O (Ln = La-Eu, except Pm = 0, 1, 2 ) have been characterized by elementalanalysis, conductivity measurement, IR spectra,1H NMR spectra, and TG-DTA techniques. In all thecomplexes, the ligand DMDO shows tridentate behavior.
