摘要
配位聚合物[Ag(L)2ClO4]是以N,N-(2-吡啶)-(4-吡啶甲基)胺和AgClO4为原料,通过水(溶剂)热法合成.X单晶结构解析显示:N,N-(2-吡啶)-(4-吡啶甲基)胺通过2-吡啶和4-吡啶甲基的N原子桥联Ag,形成菱形网格,配体N,N-(2-吡啶)-(4-吡啶甲基)胺的两个苯环互相垂直,并以Ag和分子间氢键为中心.化合物晶体数据:单斜晶系,C2/c空间群,晶胞参数a=0.848 31(6)nm,b=1.725 4(1)nm,c=1.669 9(1)nm,β=99.677(6)°,V=2.559 4(1)nm3。
Two - dimensional （2D） coordination polymers of L（ L = N, N - （2 - pyridyl） - （4 - pyridylmethyl） amine）, with empirical formulas [Ag（L）2ClO4], were prepared by hydro（solvo）thermal reactions of L and AgClO4 in mixtures of water and ethanol. Single crystal X - ray diffraction studies reveal that L ligand bridges two argentum centers with both the 4 - pyridyl and 2 - pyridyl nitrogen atoms to result in 2D rhombohedral polymeric grids. The two rings of L are essentially perpendicular to each other, likely to accommodate the coordination of both pyridyl nitrogen atoms to the Ag centers as well as the ＂intramolecular＂ hydrogen bonds. Crystal data： monoclinic space group C2/c, a = 0. 848 31（6） nm, b = 1. 725 4（1） nm, c = 1. 669 9（1） nm, β = 99. 677（6）°, V = 2. 559 4（1） nm^3.
