Abstract

The 1,2-diketone bis(2,6-diisopropylphenyl)glyoxal (LOx)0 is demonstrated to be a versatile, redox active ligand with the isolation of two early transition metal complexes, namely, octahedral [CrIII(L•)3]0 (1) (S = 0) and trigonal prismatic Na2(Et2O)2[VIV(LRed)3] (2) (S = 1/2). Structural, spectroscopic, and density functional theory (DFT) studies of these complexes, combined with a DFT investigation of the products of one- and two-electron oxidation of 2, provide insight into the factors that combine to enforce an octahedral or trigonal prismatic geometry.
