摘要：

Magnetization measurements and X-band EPR investigations on the trimeric exchange coupled Copper(II)-complex [(Cu3(C6H5CO2)4{(C2H5)2NC2H4O}2(CH3OH)2] are reported. The field dependence of the magnetization at 3.7 K is consistent with a quartet ground state and proofs that ferromagnetic exchange coupling is operative between adjacent Cu(II) - centres in the trimeric molecule. - A strong temperature dependent variation of the g value from g(eff) almost-equal-to 4.3 at liquid helium temperature to g(eff) almost-equal-to 2.6 at room temperature was observed in the EPR experiment. Different explanations for the g shift are discussed.
