Four new binuclear complexes,[Cu2(IPHTA)(phen)4](ClO4)2(1),[Cu2(IPHTA)(tmen)4](ClO4)2·H2O(2),[Co2(IPHTA)(phen)4](ClO4)2(3)and[Co2(IPHTA)(tmen)4](ClO4)2(4)(IPHTA,phen and tmen denote isophthalato dianion; 1,10-phenanthroline and N,N,N',N'-tetramethylethlenediamine respectively)were synthesized and characterized by elemental analysis,IR,electronic spectra,conductivity and variable temperature magnetic susceptibility measurements.Based on the Heisenberg model, the exchange integral,J,was found to be 2.30 cm-1for(1),3.82 cm-1for(2),8.09 cm-1 for(3)and 8.20 cm-1for(4),indicating that a weak ferromagnetic spin exchange interaction occurs between the two metal ions.The biological activities of the complexes were also tested.
