E.p.r. spectra and bonding parameters of copper(ii) complexes of 2-methyl-4,6-diacylphenols, of the dibenzoyl analogues and of some of their derivatives

Summary

The e.p.r. spectra of mononuclear copper(II) complexes of 2-methyl-4,6-diacylphenols and dibenzoylphenols, and their condensation products with 1,3-diaminopropane have been examined. The MO coefficients evaluated from e.p.r. spectral parameters indicate that the in-plane-σ, in-plane-π and out-of-plane-π bondings are significantly covalent. The e.p.r. spectra of the macrocyclic dicopper(II) complexes derived from 2-methyl-4,6-diacyl(benzoyl)phenols and 1,3-diaminopropane measured at 77 K reveal the presence of mononuclear species of axial symmetry.
