 Title    Darstellung und Eigenschaften trimerer Chlorotellurate(IV). Kristallstruktur von (CßHg^CTegCl^  
 Abstract    The trimeric chlorotellurate(IV) ion Te3Cli3~ is obtained in benzene solution as a degradation product of cubane-like tetrameric tellurium(IV) chloride Te4Cli6 and can be isolated by crystallization in the form of salts with large cations. The crystal structure of the triphenyl-methyl salt (CeHs^CTesClis (P2x/c, a = 1109.5, b = 1644.4, c = 2043.9 pm, ß = 114.50°) shows the Te3Cli3 _ ion to have approximate C3V symmetry; as a fragment of the Te4Cli6 cube it consists of three edge-sharing octahedra with a central triply bridging Cl. Bond distances Te-Cl (tripl.br.) 292.4-298.4, Te-Cl (doubl.br.) 270.6-286.3, Te-Cl (term.) 232.0-238.8 pm. The vibrational spectrum of Te3Cli3~ is discussed.
