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) 2 (dpphen) 2] was synthesized by the reaction of 4,7-diphenyl-1,10-phenanthroline with sodium fumarate and copper salts ] .CH3OH.H2O (fum = fumarate, dpphen = 4,7-diphenyl-1,10-phenanthroline) .Analysis by elemental analysis, infrared spectroscopy, thermal analysis and X-ray single crystal diffraction (A) 4.163 8 (4) nm, b = 1.323 9 (1) nm, c = 1.936 0 (1) nm, β = 117.23 (9) °; Z = 8; final deviation factor R = 0.032 7. Each Cu (II) ion in the complex is coordinated with 2 O from 4 N and 2 fps from two dpphen To form a distorted octahedral unit, and adjacent mononuclear units form a one-dimensional supramolecular ladder chain by C-H ... O hydrogen bonding, and the adjacent super-molecular chain is formed by π-π stacking between the dpphen benzene rings Two-dimensional layered structure.
