摘要

A Cu2+-doped single crystal of catena-fra"s-bis(AL(2-hydroxyethyl)-ethylenediamine) zinc(II)-tetra-m-cyanopaladate(II) [ZnPd(CN)4(C4Hl2N2O2)] complex has been investigated by electron paramagnetic resonance (EPR) technique at room temperature EPR spectra indicate that Cu2+ ions substitute for magnetically equivalent Zn2+ ions and form octahedral complexes in [ZnPd(CN)4(C4H12N2O2)] hosts. The crystal field affecting the Cu2+ ion is nearly axial. The optical absorption studies show two bands at 322 nm (30864 cm"') and 634 nm (15337 cm"1) which confirm the axial symmetry The spin Hamiltonian parameters and the relevant wave function ate determined.
