Cryomagnetic measurements have indicated that the complexes involve a trianglar-trinuclear skeleton and an antiferromagnetic spin-exchange interaction operates between copper(II) ions; exchange integrals being evaluated at −37–−45 cm<SUP>−1</SUP>.Based on the Dreiding model consideration of the complexes and the crystal structure of [Cu(tmen)(imH)<SUB>2</SUB>](ClO<SUB>4</SUB>)<SUB>2</SUB>, a trinuclear structure of the triangular skeleton with imidazolate bridges, (<U>Remark: Graphics omitted.</U>), was supposed for the complexes.
