Abstract
The electronic and molecular structures of the four-membered electron transfer series [Cr(tpy)2](PF6)n (n = 3−0) have been defined by crystallography, spectroscopy, and theoretical calculations that show sequential reduction of the terpyridine (tpy) ligands while a Cr(III) ion is retained throughout. The neutral complex is contrasted with its heavier group 6 analogues, [Mo(tpy)2] and [W(tpy)2]. In situ preparation of [Cr(tpy)2]1− gives rise to the first ever dizygoleptic complex, where the two dianionic tpy ligands are identical in all but spin state.
