The effect of glass-crystal transformation on the surrounding Sb atoms was studied using Moessbauer spectroscopic data of quenched and crystallized glasses of the system As-Se-Sb. The Moessbauer spectra of 121Sb in these glasses exhibit a positive isomer shift of 1-1.5 mm/s, relative to the crystal Sb2Se3, which is apparently caused by decreased effective coordination number of Sb and the degree of ionic bonding Sb-Se. The microheterogeneous glasses As2O3Sbx (0.4
