    Description / Table of Contents: Synthesis and Crystal Structure of the Ionic Tellurium Nitride Chloride[Te3N2Cl5(SbCl5)]+SbCl6-The title compound has been prepared by the reaction of Te2NCl5 with antimony pentachloride in CH2Cl2 suspension. It is characterized by IR spectroscopy and by a crystal structure determination. Space group P21/c, Z = 4, lattice dimensions at -70°C: a = 1535.6, b = 1259.5, c = 1572.4 pm, β = 109.30°, R = 0.031. The compound forms an ionic pair with the central group of a (TeNCl)2 molecule in which the tellurium atoms are linked by the nitrogen atoms to give a planar Te2N2 four-membered ring. One of the nitrogen atoms is coordinated by a TeCl3+ unit, the other one by an antimony pentachloride molecule. According to the IR spectra a structure like [Te2N2Cl2(TeCl4)2] is proposed for Te2NCl5.
    Notes: Die Titelverbindung wird durch Reaktion von Te2NCl5 mit Antimonpentachlorid in Dichlormethan hergestellt und durch das IR-Spektrum und eine Kristallstrukturanalyse charakterisiert. Raumgruppe P21/c, Z = 4, Gitterkonstanten bei -70°C: a = 1535,6; b = 1259,5; c = 1572,4 pm, β = 109,30°; R = 0,031. Die Verbindung bildet ein Ionenpaar, dessen Kation als zentrales Bauelement ein (TeNCl)2-Molekül enthält, in dem die Telluratome mit den Stickstoffatomen zu einem planaren Te2N2-Vierring verknüpft sind. Eines der N-Atome ist mit einem TeCl3+-Ion, das andere mit einem SbCl5-Molekül koordiniert. Aus dem Vergleich der IR-Spektren wird für Te2NCl5 eine Struktur gemäß [Te2N2Cl2(TeCl4)2] vorgeschlagen.
