摘要
以1,3-二咪唑基丙烷(1,3-bip),4,4’联苯二甲酸(H2bpdc)和Cu(NO32·3H2O为原料,在水热条件下合成了三维超分子配合物[Cu(1,3-bip)(bpdc)·3H2O]n,利用红外光谱、元素分析、粉末X射线衍射、单晶X射线衍射等技术手段对得到的样品进行了测试.单晶结构解析结果表明:Cu(Ⅱ)作为中心离子可被视为一个四连接的节点,通过配体H2bpdc,1,3-bip桥联连接形成一个二维(4,4)平面,相邻的2个(4,4)平面由存在其缝隙间的一维水分子链通过大量的分子间氢键连接形成一个稳定的三维超分子结构.另外,研究了配合物的热稳定性能.

Abstract:
The novel complex [Cu(1,3-bip)(bpdc)·3H2O]n was synthesized from 1,3-bis(imidazole) propane(1,3-bip),biphenyl-4,4'-dicarboxylic acid(H2bpdc) and copper nitrate trihydrate by hydrothermal method and confirmed via elemental analysis,IR,powder XRD,X-ray single crystal diffraction analysis.The results reveal that tiltle complex displays a (4,4) grid layer which is further reinforced through strong H-bonding with lattice solvent molecules to form a 3D supramolecular framework.
