摘要

以晶体形式合成了N，N,N ',N ' -四丁基二乙醇酰胺（TBDGA）、[Th(ReO4)4TBDGA2]、[Np(ReO4)3TBDGA2]ReO4、[UO2TBDGA2](ReO4)2和[NpO2TBDGA2]ReO4•2（C2H5OH）化合物，并用x射线衍射对其进行了表征。对Th（IV）、Np（IV）、U（VI）等化合物进行了红外光谱表征。采用紫外-可见-近红外光谱研究了TBDGA与Np（IV）和Np(V)在乙腈溶液和结晶态的络合过程。研究了Th（IV）、Np（IV）、Np(V)和U（VI）在HReO4和TBDGA萃取体系中加入亲脂醇的行为。

Investigation of New Complexes of Th(IV), Np(IV), Np(V), and U(VI) Perrhenates with N,N,N′,N′-Tetrabutyldiglycolamide

The compounds with N,N,N′,N′-tetrabutyldiglycolamide (TBDGA), [Th(ReO₄)₄TBDGA₂], [Np(ReO₄)₃TBDGA₂]ReO₄, [UO₂TBDGA₂](ReO₄)₂, and [NpO₂TBDGA₂]ReO₄•2(C₂H₅OH), were obtained in a crystalline form and characterized by X-ray diffraction. Compounds of Th(IV), Np(IV), and U(VI) also were characterized by IR spectroscopy. Complexation processes of TBDGA with Np(IV) and Np(V) in acetonitrile solution and in crystalline form were studied by UV–vis–NIR spectroscopy. Behavior of Th(IV), Np(IV), Np(V), and U(VI) in extraction systems with HReO₄ and TBDGA in saturated hydrocarbon with the addition of lipophilic alcohol was investigated.

期刊介绍： Inorganic Chemistry publishes fundamental studies in all phases of inorganic chemistry. Coverage includes experimental and theoretical reports on quantitative studies of structure and thermodynamics, kinetics, mechanisms of inorganic reactions, bioinorganic chemistry, and relevant aspects of organometallic chemistry, solid-state phenomena, and chemical bonding theory. Emphasis is placed on the synthesis, structure, thermodynamics, reactivity, spectroscopy, and bonding properties of significant new and known compounds.
