Multiple bonds and re(4f) binding energies of some rhenium halides

Abstract

AbstractExperimental results on the bombardment of some rhenium trihalides by argon ions in a photoelectron spectrometer have yielded lower‐valency rhenium halides. The presence of the compounds have been made evident by the destabilization of the Re(4f) and the relative decrease in the halogen spectral line intensities. A theoretical approach to the energy of the Re(4f) states have been studied by the MS X‐α method. The molecular model used in the calculations is made up of rhenium polyhalides in D4h symmetry having the structure Re2X (n = 2, 4, 6). A discussion is also presented on the formation of multiple bonds as a result of the overlap between the dxy orbitals of rhenium.
