Supramolecular Architecture from the Self-assembly of One-dimensionalCoordination Polymers and Hydrogen Bonds

摘要

The novel one-dimensional coordination polymer {[Cu(L)2(H2O)]· 2BF4· 6H2O}∞ [1, L=1,2-bis(4-pyridinecarboxamido)ethane] was synthesized as single crystals and characterized by means of X-ray diffraction analysis, elemental analysis, IR spectroscopy and TG measurement. Structure 1 consists of looped chains. In addition, linked by hydrogen bonds, the one-dimensional chains were transformed into three-dimensional framework, which shows channels filled with anions and uncoordinated water molecules.
