Реферат:
ESR spectra are reported for numerous chelates with a Cu-2(N, S) center; the covalent Cu--N bond is found to produce additional hyperfine splitting in solutions and glasses. MOLCAO methods are applied for D2h symmetry to estimate the degree of covalency of the o bonds to N and S, and also the effective degree of covaleney of the o bonds.
Substituents in the pyridine ring do not affect the covalency of the o bonds, but they probably affect the covalency of the out-of-plane 7r bonds from the copper to the addends. The steric hindrance produced by the substituents sometimes leads to reduction of the copper, as does the chelation. Substituents in the benzene ring do not affect
the copper-addend bonds but do determine the molecular packing. The triaxial anisotropy of the g factor is discussed in relation to details of the crystal st, ucture, including lack of equivalence of the Cu--N and Cu--S bonds.
