摘　　要：在室温下合成了3个新的配位聚合物{[Zn(4‑Nbdc)(btx)]·2H_(2)O}_(n)(1·2H_(2)O)、[Zn(btx)_(1.5)(1,3‑bdac)]n(2)和{[Zn(mbtx)(1,3‑bdc)(H_(2)O)_(2)]·H_(2)O}_(n)(3)(btx=1,4‑二(4H‑1,2,4‑三唑)苯,mbtx=1,3‑二(4H‑1,2,4‑三唑)苯,4‑Nbdc=4‑硝基邻苯二甲酸根,1,3‑bdac=间苯二乙酸根,1,3‑bdc=间苯二甲酸根),测试了配合物的单晶结构,并从元素分析、红外和粉末衍射等方面进行表征。单晶X射线衍射表明,配合物1是二维(4,4)网格结构,配合物2和3都是一维链状结构。配合物2中的π‑π作用将一维链连接成三维网格结构。在配合物3中,分子间氢键将一维链连接成二维网格,2套二维网格在分子间氢键的作用下相互穿插得到2D+2D→2D的网格结构。同时,还研究了3个配位聚合物的荧光和热稳定性。Three new coordination polymers,{[Zn(4‑Nbdc)(btx)]·2H_(2)O}_(n)(1·2H_(2)O),[Zn(btx)_(1.5)(1,3‑bdac)]_(n)(2)and{[Zn(mbtx)(1,3‑bdc)(H_(2)O)_(2)]·H2O}_(n)(3)(btx=1,4‑bis(4H‑1,2,4‑triazole)benzene,mbtx=1,3‑bis(4H‑1,2,4‑triazole)benzene,4‑Nbdc=4‑nitrophthalate,1,3‑bdac=1,3‑phenylenediacetate,1,3‑bdc=1,3‑benzenedicarboxylate),were synthesized under room temperature condition and characterized by single‑crystal X‑ray diffraction,elemental analyses,powder X‑ray diffraction.Sing‑crystal X‑ray structural analysis show that complex 1 is 2D waved(4,4)network.2 and 3 exhibit 1D chain,and the 1D chains are connected into a 3D network byπ‑πinteraction in 2.The adjacent 1D chains are connected into a 2D network by intermolecular hydrogen bond in 3.Two sets of equivalent 2D networks catenate with each other to give a 2D+2D→2D network through intermolecular hydrogen bond.Luminescence and thermogravimetric analysis of the three complexes were discussed.CCDC:2088317,1;2088318,2;2088319,3.
