英文摘要 |
A metal-organic coordination polymer, {[Cu2(pda)2(bpe)(H2O)]•3H2O}(subscript n) (1) (pda=2,6-pyridinedicarboxylate, bpe=1,2-bis(4-pyridyl) ethane), has been hydro thermally synthesized from the reaction of CuCl2 2H2O, 2,6-pdaH2 and 1,2-bis(4-pyriyl)ethane. Compound 1 is characterized by FT-infrared and single crystal X-ray diffraction. The analysis of crystal structure indicates that the compound 1 has a 3-D stacking network structure, which is formed by hydrogen-bonding (O-H…O) and π-π stacking effect of pyridine ring. Interesting, the 3-D network consists of 1-D trapezoid channels, which accommodate lattice water molecules. |
