Two types of binuclear copper(II) and nickel(II) complexes, OK-3(H), 3(H)-M<SUB>2</SUB> and [OK-m, 3(H)-M<SUB>2</SUB>]ClO<SUB>4</SUB> (<I>m</I>=2 or 3), have been synthesized, where OK-3(H),3(H) is a macrocycle composed of two 2,6-diformyl-4-methylphenol and four hydroxylamine, and OK-m,3(H) is a macrocycle composed of two 2,6-diformyl-4-methylphenol, one diamine (ethylene diamine (<I>m</I>=2) or 1,3-diaminopropane (<I>m</I>=3)), and two hydroxylamine. It was found that a very strong antiferromagnetic exchange interaction is operating between two copper(II) ions for OK-3(H), 3(H)-Cu<SUB>2</SUB> and [OK-2,3(H)-Cu<SUB>2</SUB>]ClO<SUB>4</SUB>. The complex [OK-2,3(H)-Ni<SUB>2</SUB>]ClO<SUB>4</SUB>. DMF was found to be a novel-type binuclear nickel(II) complex, in which one nickel (II) ion is diamagnetic and the other is paramagnetic.
