In chloroform, the complexes exhibit two bands in the visible and near UV regions. All complexes show room temperature magnetic moment order of 1.0 B.M. per copper atom. The X-band ESR spectrum of solution samples at room temperature shows typical hm=l transition. An electron release or withdrawing group on bridging ligand causes a great change in spin-spin interaction and is observable at Am =2 transition at half-field, which is the characteristic of dimeric unit}, keywords = {}, url = {https://jsciences.ut.ac.ir/article_31465.html}, eprint = {https://jsciences.ut.ac.ir/article_31465_1188105827d782817bd0f1599d8f305f.pdf} }
