Abstract

It has been found that the δ → δ* band in the electronic absorption spectra of a series of bis(arylimino)isoindoline dimolybdenum complexes, Mo2(BAII)(OAc)3, follows three trends. First, as the energy of the band decreases across the series its intensity increases. Second, as electron-releasing groups are added to the aryl portion of the ligand the energy of the band increases, while addition of electron-releasing groups decreases its energy. Third, as the parent aryl group becomes a better π-acceptor the band's energy decreases. These three trends are taken to indicate that the energy of the δ → °* band in this series of compounds is determined by mixing of a ligand-to-metal charge-transfer transition with the original δ → δ* transition.
