Antimony-121 Mössbauer spectroscopy of some chloro-complexes of antimony
Abstract
The 121Sb Mössbauer spectra of a number of chloroantimony salts have been examined. The presence of both SbIII and SbV in Rb2SbCl6 is confirmed. Extremely large, negative isomer shifts are obtained for [SbIIICl6]3– species and are interpreted in terms of a stereochemically inactive Ione-pair of electrons.
