采用水热法合成了双核Cu(Ⅱ)配合物[Cu2(C9 H6O4)2(C5 H5N)4·H2O].通过元素分析、红外光谱和X-射线单晶衍射对配合物进行了表征.结果表明,配合物属单斜晶系,C2/c空闻群,晶胞参数:a=1.8454620(17)nm,6=0.87957(8)nm,c=2.2995(3)nm,β=108.4620(10)°,V=3540.4(6)nm3,Z=4,Mr=817.80,Dc=1.538 g·cm-3.双核配合物呈两个对称的双四棱锥构型.双四棱锥的底面均由4个氧原子构成,N1、N2、N1A、N2A分别占据了顶点位置,完成了整个双核Cu中心的配位环境.变温磁化率数据表明,双核铜(Ⅱ)配合物分子内存在弱的铁磁性相互作用,而配合物分子间存在弱的反铁磁性相互作用.%The coordination complex [Cu2 (C9 H6 O4 )2 (Cs H5 N) 4 · H2 O] was synthesized hydrothermally and characterized by elemental analysis, IR and single crystal X-ray diffraction. The complex, crystallized in the monoclinic system in space group C2/c with cell parameters of a = 1. 84546 (17) nm, b= 0. 87957 (8) nm, c =2. 2995(3) nm, β=108.4620(10)°, V=3540.4(6) nm3, Z=4, Mr=817.80, Dc=l. 538 g · cm-3. Dinuclear complexes showed two symmetrical configuration of double four pyramid, of which the bottoms were oxygen atoms. N1, N2, N1A, N2A respectively occupied vertex positions and completed the dual-core center of the coordination environment of Cu. The variable temperature magnetic susceptibility of the complex indicated there was a weak ferromagnetic intramolecular interaction and a weak antiferromagnetic intermolecular interaction.
