合成了1,2-二(2-吡啶甲酰胺基)苯铜(Cu(bpb))配合物,以该配合物为基本构筑基元(buildingblock),通过分子间配位键及氢键相互作用形成了超分子配位聚合物.用X射线单晶衍射的方法获得了配位聚合物的单晶结构,单晶结构分析结果表明,在Cu(bpb)晶体中由于分子间一维无限伸展的弱配位键相互作用,形成了一维分子柱(molecularcolumn),许多一维分子柱沿同一方向取向、排列构成三维网络晶体,分子柱之间有氢键相连,这些氢键沿晶体学bc平面无限伸展.以Cu(bpb)为构筑基元,通过分子间一维配位键作用结合二维氢键作用,形成了超分子配位聚合物.
Synthesis of 1,2-bis (2-pyridinecarboxamido) benzene-copper (Cu (bpb)) complexes, the complex as the basic building blocks (buildingblock), through molecular coordination and hydrogen bonding interactions And the formation of a supramolecular coordination polymer. Single crystal structure of the coordination polymer was obtained by X-ray single crystal diffraction. The single crystal structure analysis results show that in the Cu (bpb) crystal, due to the one- Weakly coordinating bond to form a one-dimensional molecular column (molecularcolumn), many one-dimensional molecular column oriented in the same direction, arranged to form a three-dimensional network of crystals, hydrogen bonds between molecular columns are connected, these hydrogen bonds along the crystallographic bc plane Infinite stretching. With Cu (bpb) as the building block, a supramolecular coordination polymer is formed by the action of one-dimensional coordination bond between molecules and two-dimensional hydrogen bonding.
