Re(V) complexes formed by metal-assisted solvolysis of di-(2-pyridyl)ketone: Synthesis, X-ray studies, redox behavior and DFT calculations

► New Re(V) complexes starting from a Re(IV) precursor. ► Nucleophilic addition of 1-propanol on dpk in presence of rhenium. ► B3LYP/LANL2DZ method has proven to be appropriated in reproducing the electronic UV-Vis spectra. ► MLMLCT and LMCT have been assigned for bands simulated at the lowest and highenergy parts of the spectrum respectively.
