资源简介：
The reaction of Co2(mesityl)4 with
acetonitrile
leads to the formation of a planar, low spin, bis-β-diketiminate
cobalt(II) complex, (1-mesitylbutane-1,3-diimine)2Co (1). EPR spectroscopy, magnetic studies, and DFT calculations
reveal the Co(II) ion to reside in a tetragonal ligand field with
a 2B2(dyz)1 ground state electronic configuration. Oxidation of 1 with ferrocenium hexafluorophosphate furnishes (1-mesitylbutane-1,3-diimine)2Co(THF)2PF6 (2). The absence
of significant changes in the metal–ligand bond metrics of
the X-ray crystal structures of 1 and 2 supports
ligand participation in the oxidation event. Moreover, no significant
changes in C–C or C–N bond lengths are observed by X-ray
crystallography upon oxidation of a β-diketiminate ligand, in
contrast to typical redox noninnocent ligand platforms.
