Original language description

Mixed-ligand binuclear Cu(II) complexes involving thiodiglycolate(2-) anion and nitrogen-donor ligands in the coordination sphere of composition [(phen)(2)Cu(mu-tdga)Cu(phen)](NO3)(2).5H(2)O (1) and [(H2O)(pmdien)Cu(mu-tdga)Cu(pmdien)(H2O)](ClO4)(2) (2),where phen = 1,10-phenanthroline, H(2)tdga = thiodiglycolic acid, pmdien = N,N,N',N',N"-pentamethyldiethylenetriamine, have been prepared. Temperature dependence of magnetic susceptibility, EPR spectroscopy and single crystal X-ray analysis has been used to characterize these compounds. Magnetic susceptibility measurements over the 1.9-300 K temperature range revealed a weak antiferromagnetic interaction between two copper atoms with the exchange integral value 2J = -4.80 cm(-1) for I and -0.71 cm(-1)for 2. The bridging dianion of thiodiglycolic acid is coordinated in each of the two complexes in a different manner. (C) 2002 Elsevier Science Ltd. All rights reserved.
