Alexander V. Sienkiewicz*, Anatoliy A. Kapshuk Department of Chemistry, University of Kiev, 252017 Kiev, Ukraine Z. Naturforsch. 49b, 441-444 (1994); received September 13,1993 X-Ray, Antimony Trichloride-Phosphoryl Isothiocyanate The crystal and molecular structure of the tetrameric complex of the composition [SbCl3-OP(NCS)3]4 synthesized from SbCl3 and OP(NCS)3 in CC14 waso determined by X-ray crystallography [143 m space group, cubic system with a = 13.927(4) Ä]. The complex exhibits a tetranuclear “cage” structure with a [Sb40 4] core which consists of ̂ -bridging oxy gen and six coordinate antimony(III) atoms; the Sb-O distance, 3.060 Ä, is exceptionally long.
