Abstract

Tellurium-125 Mössbauer spectra have been recorded from some recently reported superconducting compounds Mo6−x Ru x Te8 (x=0, 0.5, 1.0, 1.5) and Mo5.5Rh0.5Te8. The spectra are characterised by single lines which probably contain contributions from the crystallographically dissimilar tellurium sites in these compounds. The trends in the linewidth and chemical isomer shift data are consistent with the enhanced polarisation of tellurium 5p electrons with increasing ruthenium content in the compounds. The results can be related to the nature of chemical bonding in the cluster of metal atoms.
