Abstract

Low-spin (S = 1) Cr(II) compounds are rare. Representative examples have been analyzed using a combination of XAS, crystallography, and DFT. These results reveal that approximately half of reported low-spin Cr(II) species are, in fact, Cr(III) species in which the ligand set has been reduced by one electron. In such cases, strong antiferromagnetic coupling of the Cr(III) center (SCr = 3/2) with the ligand-centered radical (SL = 1/2) provides the observed triplet ground state. True low-spin Cr(II) compounds are rarer than previously believed.
