Single-crystal electronic and electron spin resonance spectra of bis(ethoxyacetato)bisaquocopper(II)

Abstract

The polarised single-crystal electronic and e.s.r. spectra of bis(ethoxyacetato)bisaquocopper(II) have been measured. The correlation of the single-crystal g-values and the crystallographic data suggest a d_x²–y² ground-state for the CuO₄O′₂ chromophore. The polarised single-crystal electronic spectra are interpreted in the effective symmetry of D_2h and yield the tentative partial one-electron orbital sequence d_x²–y² > d_z² > d_yz > d_xz.
