摘要：
A metal-organic coordination polymer, {[Cu(pda)(phen)]．H₂O}n (pda= pyridine-3,4-dicarboxylate, phen = 1,10-phenanthroline), has been hydrothermally synthesized from the reaction of CuBr₂･4H₂O, NaOH, 3,4-pdaH₂ and phen. The structure was characterized by elemental analysis, FT-IR and single-crystal X-ray diffraction. The asymmetric unit of the title compound contains a five-coordinate Cu(Ⅱ) ion with a distorted square pyramidal geometry , defined by three N atoms and two carboxyl-O atoms from chelating 1,10-phenanthroline and pyridine-3,4-dicarboxylate ligands. The asymmetric unit also contains an uncoordinated water molecule. The structure exhibits a two-dimensional layer, which further forms a three-dimensional supramolecular network via weak C−H···O hydrogen bonding, π···π stacking interaction and C−H···π interaction.
