Dimerization of the molecule of the title compound, [Co(C36H54N2O2)],
an efficient dioxygen carrier, is prevented by the methyl and tert-but
yl substituents. The square-planar complex is bisected by a crystallog
raphic mirror plane, with disorder of the -CMe2-CMe2-region. Molecular
dimensions [Co-O 1.846 (2) and Co-N 1.850 (2) Angstrom] are very simi
lar to those of me related 3-tert-butylsalicylidenato complex.
