中文摘要:
      在160 °C下, 以4"-(4-吡啶基)-3,2":6",3"-三联吡啶 (3-pytpy) 为配体,Cu(OAc)2.H2O为金属盐, 通过水热法在乙腈/水的混合溶剂中合成了一个Cu(I) 配位聚合物 [Cu3(CN)3(3-pytpy)]n (1)。通过元素分析、红外光谱 (IR)、X-射线粉末衍射 (XRD) 和热重分析 (TGA) 对配合物1进行了表征,并用X-射线单晶衍射分析确定了晶体结构。结果表明, 其晶体属单斜晶系, 空间群为P21/c, Mr = 579.03, a = 7.132 (6) ?, b = 17.431 (13) ?, c = 18.388 (13) ?, β = 94.284 (14)°, V =2280 (3) ?3, F(000) =1152, Z = 4, ?(MoKα) = 2.799 mm-1, Dc = 1.687 g/cm3, 最终残差因子R1 = 0.0447 , wR2 = 0.1238。Cu(I) 均为畸变三角形配位模式, 配位原子分别为:三联吡啶配体吡啶环上的N原子、CN-基N原子和另一个CN-基C原子。CN-基桥联Cu(I) 离子形成沿ac平面对角线方向延伸的一维内消旋螺旋链 [Cu(I)-CN]n, 配体3-pytpy则进一步桥联这些一维链形成二维 “波浪型” 网络结构, 2D层以ABAB方式堆积并通过吡啶环间的π...π堆积作用拓展为三维超分子结构。
英文摘要:
      A Cu(I) coordination polymer, [Cu3(CN)3(3-pytpy)]n(1), was synthesized with 4’-(4-pyridyl)-3,2":6",3"-terpyridine and Cu(OAc)2.H2O in mixed solvents of acetonitrile and water under hydrothermal conditions at 160 °C. 1 was characterized by element analysis, IR spectrum, thermogravimetric analysis (TGA) and X-ray powder diffraction (XRD). Single-crystal X-ray analysis reveals that 1 crystallizes in monoclinic, space group P21/c, with Mr = 579.03, a = 7.132 (6) ?, b = 17.431 (13) ?, c = 18.388 (13) ?, β = 94.284 (14)°, V =2280 (3) ?3, F(000) =1152, Z = 4, ?(MoKα) = 2.799 mm-1, Dc = 1.687 g/cm3, R1 = 0.0447 ,wR2 = 0.1238. Each Cu(I) atom exhibits a 3-connecting mode, including two N atoms from a 3-pytpy ligand and a CN- group, respectively, and one C atom from another CN- group. Cu(I) ions bridged by CN- groups to give a 1D meso-helical chains along the diagonal direction of the ac plane. And the chains are further linked by 3-pytpy ligands into a wave-like 2D network. The neighboring 2D layers are interconnected by the strong π…π interactions and stacked in an ABAB fashion to give a 3D supramolecular network. CCDC: 1053592.
