Mean amplitudes of vibration of molecules and ions with interhalogen bonds and related species

Mean amplitudes of vibration of molecules and ions containing interhalogen bonds are reviewed and critically analyzed. The presented information comprises pure interhalogen compounds as well as oxohalides. Correlations between mean amplitude values and structural and bond properties are discussed. Comparisons with data of related – specially isoelectronic – species are also performed. Characteristic ranges for the mean amplitudes of vibration for halogen–halogen and halogen–oxygen bonds could be established. The presented and discussed results are also of central importance for the analysis and interpretation of electron diffraction studies.
