摘要
利用螯合配体4,7-二苯基-1,10-邻菲罗啉与反丁烯二酸钠及铜盐反应合成了一种新型超分子配合物[Cu(fum)(dpphen)2].CH3OH.H2O(fum=反丁烯二酸根,dpphen=4,7-二苯基-1,10-邻菲罗啉).通过元素分析、红外光谱、热分析和X射线单晶衍射等技术对其进行了表征.配合物属单斜晶系,空间群C2/c;晶胞参数:a=4.163 8(4)nm,b=1.323 9(1)nm,c=1.936 0(1)nm,β=117.23(9)°;Z=8;最终偏离因子R=0.032 7.配合物中每个Cu(Ⅱ)离子与来自两个dpphen的4个N和一个fum的2个O配位,形成畸变的八面体结构单元.相邻单核单元通过C—H…O氢键作用形成一维超分子梯状链,毗邻的超分子链通过dpphen上苯环间的π-π堆积作用形成二维层状结构.
A novel supramolecular complex, [ Cu ( fum ) (dpphen) 2 ]· CH3OH· H2O ( fum = fumarate dianion, dpphen = 4, 7-diphenyl-1, 10-phenanthroline), has been prepared from the reaction of bidentate ligand (dpphen), fumarate with CuCl2, and were characterized by element analysis, IR, thermal analysis and X-ray diffraction technique. The results show that the complex is monoclinic, withspace group C2/c, α=4.163 8(4) nm, b=1.323 9(1) nm, c=1.936 0(1) nm, β= 117.23(9)°; Z = 8 and R = 0. 032 7. Each Cu( Ⅱ ) atom is coordinated by four nitrogen atoms from two different dpphens and two oxygen atoms from fumarate with a distorted octahedron geometry. In the complex, a 1D supramolecular ladder-shaped chain is constructed by C-H…O hydrogen bonds between two mononuclears, furthmore, the chains are assembled by π-π stacking interactions of aryl (dpphen) to furnish a 2D suprarnolecular layer structure.
