    摘要:
    Examination of two crystalline forms of tris(methyl-acetylacetonato)cobalt(III), [Co(C6H9O2)(3)], indicate that the cobalt ion is coordinated by three chelating ligands resulting in octahedral complexes. The first crystal form is cubic with the Co atom lying on a threefold axis, and the crystal contains a small amount (similar to 1.65 molecules) of disordered water. The second crystal form is triclinic with two unique complexes.

The kD and kep values of the NO2acac complex are ca. 104 and ca. 106 times, respectively, larger than those of the CH3acac complex. The effect of substituents is electronic and the Hammett relationship was found to hold for both deuteration and epimerization rates. The
