Molecular Structures of Dibromo[(E)2-bromo-2-phenylvinyl]-(phenyl) tellurium (IV) and Dibromo [(Z)-2-bromo-2-phenyl-vinyl] (p-tulyl) tellurium (IV) hydrate methanolate
Abstract
The structures of title compounds, [TeBr2(C8H6Br)(C6H5)] (I) and [TeBr2(C8H6Br)(C7H9)](H2O)(CT3OH) (II), have been determined by X-ray diffraction. The structures confirm that E- or Z-type configuration of vinylic telluride depends on the polarity of solvent employed. In either structure, Te atom is in a trigonal dipyramide configuration with the lone pair of electrons in the equatorial position.
