Abstract
The imidazole-bridged binuclear copper(II) complex, [(Cl)(2)(imH)(2)Cu (imH)(2)Cu(bipy)(Cl)(2)] and the trinuclear copper (II) complex [(Cl)( 2)(bipy)Cu(imH)(2)Cu(imH)(2)Cu(bipy)(Cl)(2)] have been synthesized by direct coupling between [Cu(imH)(4)(Cl)(2)] and [Cu(bipy)Cl-2] in the appropriate stoichiometric ratios. The complexes show subnormal magnet ic moments and e.p.r. spectra, characteristic of the triplet state. Th e antiferromagnetic coupling constant, J, has been obtained for both t he complexes.
