The structures of title compounds, [TeBr 2 (C 8 H 6 Br)(C 6 H 5 )] (I) and [TeBr 2 (C 8 H 6 Br)(C 7 H 9 )](H 2 O)(CT 3 OH) (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.
