Abstract

Mixed ligand Ln₂Cu₂ tetranuclear complexes, [{LnCu(L4)(L5)(NO₃)₂}₂] (L4^- is a Schiff base ligand derived from o-vanilate, L5^2- is a nitromethyl derivative of L4^-; LnGd(4), Tb(5), and Dy(6)), were synthesized by reacting the corresponding dinuclear complexes [LnCu(o-vanilate) ₂(NO₃)₃] with ethylamine in a nitromethane solution. From detailed studies of magnetic anisotropies 5 was shown to behave as an SMM, whereas 6 was not an SMM.
