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 TeVI[OTeIV(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 TeVI[OTeIV(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.
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.
