Abstract

The complex (bis(2,6-diisopropylphenyl)pentane-2,4-ketiminato)(9,10-dihydro-9,10-(ethenediolato)anthracene)(tetrahydrofuran)chromium(III) (1) has been synthesized and structurally characterized. Complex 1 crystallizes in the spacegroup Cc with the crystal cell parameters a = 22.285 (3) Å, b = 9.3317 (13) Å, c = 40.782 (6) Å, β = 99.338 (3)°, V = 8369 (2) Å3, and Z = 8. Two symmetry unique complex molecules were located in the asymmetric unit making Z′ = 2. The chromium atoms display square pyramidal coordination with THF located in the axial position. The previously neutral α-diketone moiety has been reduced by two electrons to an enediolate group with a corresponding increase of oxidation state of the chromium center.

Graphical Abstract

The strong reducing ability of a chromium(I) β-diketiminate fragment is demonstrated by the reduction of a α-diketone to an enediolate dianion.
