本文合成了四个以邻苯二甲酸阴离子为桥联配体的新型希土双核配合物［Ｌｎ２（Ｐｈｔｈ）（ＮＯ２－ｐｈｅｎ）４］（ＣｌＯ４）４·ｘＨ２Ｏ［Ｌｎ＝Ｇｄ、Ｔｂ、Ｈｏ、Ｅｒ，ＮＯ２－Ｐｈｅｎ＝５－硝基－１，１０－菲咯啉，Ｐｈｔｈ＝邻苯二甲酸阴离子）．经元素分析，ＩＲ、电导、电子吸收光谱，表征了配合物，测定了［Ｇｄ２（Ｐｈｔｈ）（ＮＯ２－ｐｈｅｎ）４］（ＣｌＯ４）４·４Ｈ２Ｏ的变温磁化率（４～３００Ｋ），其数值用最小二乘法与理论方程拟合，求得交换参数Ｊ＝－２．１８ｃｍ－１，表明Ｇｄ（Ⅲ）－Ｇｄ（Ⅲ）离子间存在较弱的反铁磁交换相互作用．
In this paper, four new rare earth dinuclear complexes [Ln2 (Phth) (NO2-phen) 4] (ClO4) 4 · xH2O [Ln = Gd, Tb, Ho, Er, NO2-Phen = 5-nitro-1,10-phenanthroline, Phth = Phthalate anion). The temperature-dependent magnetic susceptibility (4 ~ 300K) of [Gd2 (Phth) (NO2-phen) 4] (ClO4) 4 · 4H2O was determined by elemental analysis, IR, conductivity and electron absorption spectroscopy. The least squares method was fitted with the theoretical equation to obtain the exchange parameter J = -2.18cm-1, indicating that there was a weak anti-ferromagnetic exchange interaction between Gd (Ⅲ) -Gd (Ⅲ) ions.
