Abstract: Four new binuclear complexes, [Cu2 (TPHA) (NO2-Phen)4] (ClO4)2 · H2O(1), [Cu2(TPHA)(Me-bpy)1](ClO4)2(2),[Mn2(TPHA)(NO2-Phen)1](ClO4)2·2H2O(3) and [Mn2(TPHA)(Me-bpy)4](ClO4)2(4), where TPHA, NO2-Phen and Me-bpy denote tereph-thalato dianion, 5-nitro-1, 10-phenanthroline and 4, 4'-dimethyl-2, 2'-bipyridine respectively, were synthesized and characterized by elementary analysis, IR, electronic spetra and variable temperature magnetic susceptibility.Variable temperature (4.2-300 K) magnetic susceptibility data for the complexes show that there exists the antiferromagnetic exchange interaction between the two metal ions with J(cm-1) values of -5.04(1),-6.52(2),-0.68(3) and -0.73(4).
