摘　　要：合成和表征了4种新型配合物[Cu_2(TPHA)(NO_2-Phen)_1](ClO_1)_2·H_2O、[Cu_2(TPHA)(Me-bpy)_1](ClO_1)_2、[Mn_2(TPHA)(NO_2-Phen)_1](ClO_1)_2·2H_2O和[Mn_2(TPHA)(Me-bpy)_1](ClO_1)_2(TPHA:对苯二甲酸根阴离子;NO_2-Phen:5-硝基-1,10-菲绕啉;Me-bpy:4,4’-二甲基-2,2’-联吡啶).测定了配合物的变温磁化率,并求出了交换积分J分别为-5.04、-6.52、-0.68及-0.73cm^(-1).Four new binuclear complexes, [Cu2 (TPHA) (NO2-Phen)4] (C104)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).
