The antimony-121 Mössbauer effect. Part II. The spectra of some halide complexes of antimony(III)

Abstract

The antimony-121 Mössbauer parameters of a number of fluoride, chloride, bromide, and iodide complexes of antimony(III) are reported. The chemical isomer shift data are discussed in terms of the formation of complexes from the parent antimony(III) halide. The magnitudes and signs of eQV_zz are interpreted on the basis of the known structures and of the likely distribution of electron density around the antimony nuclei.
