Electronic origin of the structural versatility in linear trichromium complexes of dipyridylamide
Abstract
Spin unrestricted DFT calculations on Cr3(dpa)4Cl2 (dpa = dipyridylamide) suggest that the linear (Cr3)6+ metal framework could adopt either a symmetric conformation, or a strongly nonsymmetric one, depending on the nature of the spin coupling between the localized metal electrons.
