Abstract

This work describes the reaction of the potentially tetradentate Schiff-base ligand -(2-pyridylmethy)-3-methoxysalicylaldimine (HL) with UO(OCMe)·2HO and UO(NO)· 6HO in MeOH in the absence or presence of an external base, respectively. The product from these reactions is the mononuclear complex [UO(L)] (). Its structure has been determined by single-crystal, X-ray crystallography. The anionic ligand adopts two different coordination modes (1.1011, 1.1010; Harris notation) in the complex. The new compound was fully characterized by solid-state (IR, Raman and Photoluminescence spectroscopies) and solution (UV-Vis and H NMR spectra, conductivity measurements) techniques.

摘要

这项工作描述了潜在的四齿席夫碱配体-（2-吡啶甲基）-3-甲氧基水杨醛亚胺（HL）分别在不存在或存在外部碱的情况下，于甲醇中与UO(OCMe)·2HO和UO(NO)·6HO的反应。这些反应的产物是单核配合物[UO(L)]（）。其结构已通过单晶X射线晶体学确定。在该配合物中，阴离子配体采用两种不同的配位模式（1.1011，1.1010；哈里斯表示法）。该新化合物通过固态（红外、拉曼和光致发光光谱）和溶液（紫外可见和核磁共振光谱、电导率测量）技术进行了全面表征。
