Abstract: | The Crystal Structure of [TeCl3(15-crown-5)]SbCl6 The title compound is synthesized by the reaction of tellur tetrachloride, 15-crown-5 and antimony pentachloride in acetonitrile solution, forming colourless crystals, which were characterized by IR spectroscopy and an X-ray structure determination. Space group Pnma, Z = 4, 1966 observed unique reflections, R = 0.072, Rw = 0.052. The compound forms ions [TeCl3(15-crown-5)]+ and SbCl6?; in the cation the tellurium atom is eightfold coordinated by the three chlorine atoms and the five oxygen atoms of the crownether molecule (Te? O bond lengths 266 and 279 pm). |
