利用水熱合成含吡啶雙羧酸及雙吡啶之銅(Ⅱ)金屬配位聚合物及其結構分析

Hydrothermal Synthesis and Structure of the Copper (Ⅱ) Coordination Polymer based on Pyridinedicarboxylate and Bipyridine

將2,6-吡啶雙羧酸加Cu(OAc)2、Ho2O3及4,4′-雙吡啶加水混合，利用水熱合成反應，得到銅(Ⅱ)的配位高分子化合物，其化學式為[Cu6(pda)6(bp)3(H2O)6]2(1)(pda=2,6-吡啶雙羧酸,bp=4,4′-雙吡啶)。利用X-Ray晶體繞射儀、FT-IR光譜儀測定產物晶體結構及性質，結果顯示化合物1包含兩個未鍵結的六核錯合物，經由分子間的氫鍵(C-H---O)作用，以及吡啶環之間的π-π吸引力，使得此晶體自組裝成3-D無限延伸的網狀結構。

A novel complex, [Cu6(pda)6(bp)3(H2O)6]2 (1) (pda = 2,6-pyridinedicarboxylate, bp = 4,4'-bipyridine), is hydrothermally synthesized from the reaction of Cu(OAc)2 , pdaH2, Ho2O3 and 4,4′-bipyridine. Compound 1 is characterized by FT-infrared and single crystal X-ray diffraction. Compound 1 structures of both polymers have been determined by single crystal X-ray diffraction. X-ray structure analyses show the compound 1 is composed of two complex ions bridged through hydrogen bonds. The compound 1 was assembled into 3-D networks via C–H⋅⋅⋅O hydrogen bond and π-π stacking interactions.
