Antimony-121 Mössbauer spectroscopy of some cyanide adducts of antimony pentachloride
Abstract
121
Sb Mössbauer spectra have been measured at 4·2 K in some cyanide adducts SbCl5,NCR (R = Me, Cl, But, Ph, Et, CH2Cl, CCl3, CHCH2). Hyperfine interactions deduced from transmission integral analysis of the spectra are interpreted in terms of the varying degree of electron transfer from the cyanide to the antimony atom. The results are discussed in combination with data from nuclear quadrupole resonance and vibrational spectroscopy studies.
