英文摘要 |
The title compound, [Cu(pdaH)2].2H2O (1) (pdaH2 = pyridine-2, 4-dicarboxylic acid), was obtained by the reaction of copper (Ⅱ) chloride dihydrate with pdaH2 and 1, 10-phenanthroline. The title compound was characterized by single crystal X-ray diffraction, FT-IR spectroscopy, elemental analysis and differential scanning calorimeter. The copper (Ⅱ) ion is coordinated by two oxygen atoms from two pdaH2 ligand are belong to carboxyl acid (at pyridine 2 position), two nitrogen atoms from two pdaH2 ligand and two uncoordinated water molecules, respectively, showing a square-planar geometry. In addition, the intermolecular O-H⋅⋅⋅O hydrogen-bonding and C-O⋅⋅⋅π, O-H⋅⋅⋅π stacking interactions further extend the title complexes, forming 3-D structures. |
