摘要：
Crystals of cis-(Me4Sb)(2)[Ph2Sb2I6] (la) are formed by reaction of PhSbI2 and Me4SbI in ethanol/petroleum ether at -7 degrees C. In ethanol/acetone crystals of trans-(Me4Sb)(2)[Ph2Sb2I6] acetone (Ib) form. The X-ray crystal structure analyses reveal that both isomers consist of tetrahedral cations and of dimeric anions with the geometry of two edge sharing tetragonal pyramids. The phenyl groups possess apical cis (la) or trans (Ib) positions relative to the I2SbI2SbI2 plane. The acetone molecules in Ib are non coordinating.
