将CuSO4.6H2O与H2phth(邻苯二甲酸)反应,得到配合物[Cu2(phth)2(H2O)2]∞.通过EA、IR和TG对其进行了表征,单晶X射线衍射对它的结构进行了确证.结构分析表明:Cu(Ⅱ)处在由6个氧原子配位的变形八面体配位几何构型之中,并通过羧基基团的配位作用,构成一维的配位聚合结构,其中邻苯二甲酸配体表现出两种配位形式.TG结果表明:配合物具有很好的热稳定性.磁性研究表明:配合物中的Cu2+与Cu2+之间没有直接的自旋-自旋磁交换作用,只是表现出普通的顺磁行为,根据Curie-Weiss定律拟合得C=0.25 cm3.K.mo1-1,θ=0.5 K.
A complex,[Cu2(phth)2(H2O)2]∞,(H2phth=Phthalic acid),has been synthesized through the reaction of Cu2+ salt with phthalic acid.It has been characterized by EA,IR,TG and single crystal X-ray diffraction.X-ray single-crystal diffraction shows that each Cu(Ⅱ) atom is coordinated by six oxygen atoms in a octahedral geometry and the phth anion adopts two types of coordination fashion to bridge Cu(Ⅱ) atoms.No spin-spin interaction between the adjacent Cu atoms in the polymeric chain was observed from the magnetic experiments.The complex obeys the Curie-Weiss law with Weiss constant C=0.25cm3·K·mo1-1,θ=0.5 K in the high-temperature region.
