Abstract

The reaction of telluric acid with di-organotellurium di chloride (R₂TeCl₂) and tri-organoantimony dichloride (R₃SbCl₂) has been carried out in binary solvent using solvothermal synthesis method and isolated high-phase purity compounds. Single crystal X-ray diffraction studies revealed the formation of a novel mixed valent tellurium (VI) containing clusters Te^VI[OTe^IV(p-MeOC₆H₄)₂Cl]₆ (R = p-MeOC₆H₄) (1) and [Te(µ₂-O₅SbPh₃)(OSbh₃Cl)]₂ (2). Cluster 1 has a central Te(VI) atom which is connected to six oxygen atoms octahedrally, further this oxygens bridging to six other tellurium atoms (IV). Cluster 2 is an octanuclear heterometallic cluster that is built up of a [Te (VI), Sb (V)] Te₂Sb₆ oxo-centered butterfly core. The products have been analyzed using single crystal X-ray diffractions, powder X-ray diffraction, and IR spectroscopic and analytical methods.

Graphical Abstract

A star-shaped mixed valent tellurium [(VI), (IV)] cluster Te^VI[OTe^IV(p-MeOC₆H₄)₂Cl]₆ (1) has been synthesized in binary solvent (Acetonitrile/DMF) medium. Cluster [Te(µ₂-O₅SbPh₃)(OSbh₃Cl)]₂ (2) is an octanuclear heterometallic assembly built up of Te (VI) and Sb (V) ions, containing an oxo-centered butterfly core.

星形 Te(VI)-Te(VI)配合物和八核异金属 Te2Sb6 氧簇

采用溶热合成法，在二元溶剂中进行了碲酸与二有机碲二氯化物（R2TeCl2）和三有机锑二氯化物（R3SbCl2）的反应，并分离出了高纯度化合物。单晶 X 射线衍射研究揭示了一种新型含混合价碲 (VI) 簇 TeVI[OTeIV(p-MeOC6H4)2Cl]6 （R = p-MeOC6H4）(1) 和 [Te(µ2-O5SbPh3)(OSbh3Cl)]2 (2)的形成。簇 1 具有一个中心 Te（VI）原子，该原子与六个氧原子呈八面体连接，氧原子再与其他六个碲原子（IV）桥接。簇 2 是由[Te（VI），Sb（V）] Te2Sb6 氧心蝶形核构成的八核异金属簇。利用单晶 X 射线衍射、粉末 X 射线衍射、红外光谱和分析方法对产物进行了分析。图解摘要在二元溶剂（乙腈/DMF）介质中合成了星形混合价碲[(VI), (IV)]簇 TeVI[OTeIV(p-MeOC6H4)2Cl]6 (1)。簇[Te(μ2-O5SbPh3)(OSbh3Cl)]2 (2) 是由 Te (VI) 离子和 Sb (V) 离子组成的八核异金属集合体，含有一个以氧化物为中心的蝶形核心。

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
