Abstract
Four novel trinuclear copper(II) complexes have been synthesized, namely {[Cu(ebo)][Cu(L)] 2} (ClO 4) 2, where ebo denotes 1,2-ethylenebis(oxamido) and L is 2,2′-bipyridyl (bpy), 4,4′-dimethyl-2,2′-bipyridyl (Me 2 bpy), 1,10-phenanthroline (phen) or 5-nitro-1, 10-phenanthroline (NO 2-phen). Based on IR, elemental analyses, conductivity measurements and electronic spectra these complexes are proposed to have oxamidobridged structures and to consist of three copper(II) ions in which each metal ion has a square planar environment. The temperature dependence of the magnetic susceptibility of [Cu(ebo)][Cu(NO 2-phen)] 2 (ClO 4) 2·2H 2O has been studied in the 4–200 K range, giving the exchange integral J = −80.9 cm −1. The result revealed the operation of an antiferromagnetic spin-exchange interaction between the adjacent copper ions.
