Abstract

Two new cadmium-substituted polyoxovanadates of [Cd(dien)2]2[(dien)CdAs8V13O41(H2O)].4H2O and [Cd(en)2]2[(en)2Cd2As8V12O40] (2), where dien is diethylenetriamine and en is ethylenediamine, have been hydrothermally synthesized and structurally characterized by elemental analyses, IR spectra, EPR spectra, XRD spectra, TG analyses, magnetic properties, and X-ray crystallography. Single-crystal X-ray diffraction analyses reveal that compounds 1 and 2 possess a discrete and 1D structure, respectively. The former contains an inorganic-organic hybrid monocadmium-substituted polyoxovanadate cluster unit that is derived from the well-known {As8V14O42} cluster, whereas the latter is composed of an inorganic-organic hybrid bicadmium-substituted polyoxovanadate cluster unit that is derived from the well-known {As8V12O40} cluster.

摘要

水热合成了两种新的镉取代多钒酸盐[Cd(dien)2]2[(dien)CdAs8V13O41(H2O)].4H2O和[Cd(en)2]2[(en)2Cd2As8V12O40] (2)，其中dien为二乙烯三胺，en为乙二胺，并通过元素分析、红外光谱、电子顺磁共振光谱、X射线衍射光谱、热重分析、磁性和X射线晶体学对其进行了结构表征。单晶X射线衍射分析表明，化合物1和2分别具有离散结构和一维结构。前者包含一个无机-有机杂化单镉取代多钒酸盐簇单元，该单元源自著名的{As8V14O42}簇，而后者由一个无机-有机杂化双镉取代多钒酸盐簇单元组成，该单元源自著名的{As8V12O40}簇。
