The electron paramagnetic resonance spectra Of Cu2+ in [Cd(sac)(2)(H2O)(4)](.)2H(2)O and [Cd(sac)(2)(HydEt-en)(2)] (HydEt-en = N-(2-hydroxyethyl)-ethylenediamine) single crystals and powder were examined at room temperature. A detailed study of the spectra of the compounds indicates the replacement of Cd2+ in the host compounds with Cu2+. [Cd(sac)(2)(H2O)(4)] (.) 2H(2)O shows the presence of two sites for Cu2+ and [Cd(sac)(2)(HydEt-en)(2)] has a single site. The principal values for the g-tensor and the hyperfine tensor for Cu2+ in the two compounds were obtained. The Cu2+ ion was found to be mostly in the 3d(x2-y2) orbital and the ground-state wavefunction of [Cd(sac)(2)(HydEten)(2)] was constructed.
