柔性配体1,4-二亚甲基咪唑-2,3,5,6-四甲基苯(p-bitmb)与不同金属盐发生水热反应,得到两个新的配位聚合物{[Cu(Ⅰ)2Cl( p-bitmb)2][Cu(Ⅰ)Cl2]· H2O}n(1)和[CoCl2( p-bitmb)]n(2).用单晶X-射线,元素分析,FTIR,热重分析对两个化合物进行了表征.配合物1和2都具有一维链状结构,但1中的一维链进一步通过π-π堆积和氢键作用拓展成二维超分子结构.值得注意的是配合物1合成过程中的Cu(Ⅱ)被还原为Cu(Ⅰ),推测是由于在高的合成温度下被具有还原性的咪唑环还原引起的.

In this paper two new coordination polymers [[Cu(Ⅰ)2Cl(p-bitmb)2][Cu(Ⅰ)Cl2]· H2O]n (1),[CoCl2(p-bitmb)]n(2) have been solvothermally synthesized by using a new flexible ligand 1,4-bis (imidazo-l-ylmethyl)-2,3,5,6-tetramethylbenzene (p-bitmb) and MCl2 salt (M=Cu or Co).Compounds 1 and 2 have been characterized by single crystal X-ray diffraction analyses,elemental analyses,IR spectra and thermogravimetric analyses.Both 1 and 2 consist of 1D infinite coordinative chains,but a 2D supramolecular structure of 1 is constructed through hydrogen-bond and aromatic π-π interactions.It is interesting that Cu(Ⅱ) was reduced to Cu(Ⅰ) in the synthesis of 1,which is probably promoted by the high synthetic temperature and the reductive property of the imidazole ligand.CCDC:808064,1; 853579,2.
