摘要
应用溶液法合成标题配合物[Cu(bpy)(H2O)(mal)].H2O(bpy=2,2'-联吡啶,mal=丙二酸)。通过X射线衍射法测定配合物的晶体结构,其晶体学数据如下:三斜,P-1,a=7.132(1),b=10.404(2),c=10.694(2);α=105.85(3)°,β=104.53(3)°,γ=105.28(3)°,V=690.4(2)(3),Dc=1.721 g.cm-3,Z=2。在标题化合物中,中心Cu(Ⅱ)离子配位数为5,构成CuN2O3四方锥配位模式。并对其进行红外光谱、元素分析、粉末X射线衍射、差热、磁性等表征。配合物的3D拓扑分析可简化含有(4,6)-双节点fsc拓扑网络,配合物在2～300 K区间遵循韦斯定理χm(T-0.27)=0.85cm3.K.mol-1,磁性测试结果表明Cu2+离子之间存在铁磁作用。
The title compound [ Cu （ bpy ） （ H20 ） （ mal ） ] - H2O （ bpy = 2,2＇-Bipyridine, mal = malonic acid） was synthe- sized in water-methanol solution. The crystal structure was determined by single-crystal X-ray diffraction analysis. The crystal belongs to triclinic with space group P-1,a = 7. 132 （1）°, b = 10.404（2）°,c = 10.694（2） °,α = 105.85 （3）°,β = 104.53（3）°,T =105.28（3）°,V=690.4（2）（A3）,Dc = 1. 721 g.cm-3 ,Z =2. In the title complex,the Cu（ II ） ion is five-coordinated,forming a square pyramidal CuN203 coordi- nation environment. The complex was characterized by IR spectrum, Elemental analysis, X-ray powder diffraction, thermal analysis, magnetic property. The 3D topology analysis of the title compound showed an uncommon 4,6-connected binodal fsc topology. The complex is ferromagnetic and obeys Curie-Weiss law with X, （ T - 0. 27 ） = 0. 85 cm3 · K- mol - 1 between 2 · 300 K（Xm being magnetic susceptibility per one Cu2＋ ion）.
