Abstract

The Cu(II) complexes in [Cu(bipy)2X](ClO4) and [Cu(phen)2X](ClO4) were studied by ESR spectroscopy at ν=9.8 GHz and optical absorption at 7000–20,000 cm−1. The axially symmetrical g factors, corresponding to the g‖<g⊥, were established for the distorted trigonal bipyramidal coordination of Cu(II) with C 2v symmetry. Analysis of the possible vibrational distortions of the complex showed that the axial symmetry of the g factor is a consequence of “orientational averaging” realized for an electronic vibrational state with a “two-well” adiabatic potential at the final height of the barrier and vibrational frequency greater than the ESR frequency.
