Abstract
Four new trinuclear copper(II) complexes, [Cu(phen)(NBzIm)] (ClO4) (1) , [Cu(bpy)(NBzIm) ] (ClO4) (2), [Cu(Me2-bpy)(NBzIm)](Ac).1/2H2O (3) an d [Cu(Me2-bpy)(Im)](ClO4).1/2H2O (4) (phen=1,10-phenanthroline, bpy = 2,2'-bipyridine, NBzIm = 6-nitrobenzimidazolate ion, Im = imidazolate ion) have been prepared and characterized by variable temperature magn etic susceptibility measurements. A weak antiferromagnetic spin exchan ge interaction operates between copper(II) ions, exchange integrals ev aluated as J = -23.82 cm-1 for (1) and J = -21.91 cm-1 for (2).
