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

Abstract

Experimental 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-a method. The molecular model used in the calculations is made up of rhenium polyhalides in D, symmetry having the stn~cture R%X;-(n = 2,4,6). A discussion is also presented on the formation of multiple bonds as a result of the overlap between the d, orbitals of rhenium.

Covalent-Organic Frameworks Composed of Rhenium Bipyridine and Metal Porphyrins: Designing Heterobimetallic Frameworks with Two Distinct Metal Sites

“…Analysis of the COF-Re Re 4f spectrum (Figure A) showed two peaks with binding energies of 44.2 and 41.9 eV, corresponding to Re 4f 5/2 and 4f 7/2 . These peaks and binding energies are similar to those of the previously reported rhenium­(I) bipyridine complexes. ,, There are also three nitrogen peaks present in the N 1s region at 400.5, 399.6, and 398.1 eV (Figure S27), which are assigned to the three unique nitrogen environments in the framework.…”
