基于1-丁基苯并咪唑和对苯二甲酸混合配体的锌(Ⅱ)和铜(Ⅱ)一维配位聚合物:晶体结构和弱相互作用

摘要

用1-丁基苯并咪唑和对苯二甲酸与Zn(NO3)2· 6H2O或Cu(NO3)2· 3H2O反应合成了两个锌(Ⅱ)和钴(Ⅱ)的一维配位聚合物[Zn(L)2(TP)]n(1)和[Cu(L)2(TP)]n(2)(L=1-丁基苯并咪唑,TP=对苯二甲酸根).配位聚合物1和2通过C-H…O或O-H…O氢键形成了二维超分子层.测定了L,1和2的荧光发射光谱.%The two 1D coordination polymers [Zn(L)2(TP)]n (1) and [Cu(L)2(TP)]n (2) (L=1-butylbenzimidazole,TP=terephthalate ion) have been prepared via the reaction of 1-butylbenzimidazole,terephthalic acid and Zn(NO3)2·6H2O or Cu(NO3)2·3H2O,respectively.The structures of these complexes were characterized by X-ray diffraction analysis.In the crystal packings of coordination polymers 1 and 2,2D supramolecular layers are formed through C-H…O or O-H…O hydrogen bonds,respectively.The fluorescence emission spectra of L,1 and 2 are described.CCDC: 899947,1; 899948,2.
