將2,6-吡啶雙羧酸加CuCl2•2H2O及1,2-雙（4-吡啶）乙烷加水混合，利用水熱合成反應，得到銅(II)的配位高分子聚合物，其化學式爲｛[Cu2(pda)3(bpe)(H2O)]•3H2O｝(下標 n)(1)（pda=2,6-吡啶雙羧酸，bpe-1,2-雙（4-吡啶）乙烷）。利用X-Ray晶體繞射儀及FT-IR光譜測定產物晶體結構及性質，結果顯示化合物1，經由分子間的氫鍵(O-H---O)作用，以及吡啶環之間的π-π吸引力，此晶體自組裝成3-D無限延伸的網狀結構。此3-D的網狀結構具有一維的不規則孔洞，可容納晶格水分子。

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.
