合成和表征了３种新型的对苯二甲酸根桥联的双钴（Ⅱ）配合物：［Ｃｏ２（ＴＰＨＡ）（ＮＯ２－ｐｈｅｎ）４」（ＣＩＯ４）２·Ｈ２Ｏ（１），［Ｃｏ２（ＴＰＨＡ）（ｔｍｅｎ）４］（ＣＩＯ４）２（２）和［ＣＯ２（ＴＰＨＡ）（ｔｍｄ）４」（ＣＩＯ４）：（３）．经元素分析、红外光谱、电子光谱、电导和磁性测量等手段推定配合物具有对苯二甲酸根桥联结构，Ｃｏ（Ⅱ）离子处于畸变的八面体环境．测定了配合物（１）和（２）的变温（４～３００Ｋ）磁化率，其数值与自旋哈密顿算符ｈ＝－２ＪＳ１·Ｓ２导出的磁方程拟合，求得交换积分Ｊ分别为－２．９５ｃｍ－１（１）和－１．２４ｃｍ－１（２），表明双核配合物中金属离子间存在弱的反铁磁性超交换作用．
Three novel bis (Ⅱ) complexes of terephthalic acid bridged were synthesized and characterized: [Co2 (TPHA) (NO2-phen) 4 “(CIO4) 2 · H2O ) (Tmen) 4] (CIO4) 2 (2) and [CO2 (TPHA) (tmd) 4 ”(CIO4) :( 3). The structure of the complex was observed to be terephthalic acid bridged by means of elemental analysis, infrared spectroscopy, electron spectroscopy, conductance and magnetic measurements. The Co (Ⅱ) ion was in a distorted octahedral environment. The magnetic susceptibility of the complexes (1) and (2) was measured and their values were fitted to the magnetic equations derived from the spin Hamiltonian h = -2JS1 · S2. The exchange integrals J were -2.95cm-1 (1) and -1.24cm-1 (2), respectively, suggesting weak antiferromagnetic meta-exchange between the metal ions in the binuclear complex.
