摘要
利用一类研究相对有限的混合配位点配体(同时含有间苯二甲酸和四氮唑有机片段分别提供N-/O-配位点)与不同的金属离子配位得到3个配位聚合物([Eu(TZI)(H_(2)O)_(5)]·2H_(2)O(1)、[Tb(TZI)(H_(2)O)_(4)]·5H_(2)O(2)和[Cd(H_(2)TZPI)2(H_(2)O)_(4)]·H_(2)O(3)).结构分析表明化合物1和2具有相似的1D双链结构,而化合物3具有0D结构,它通过非共价相互作用(O—H…N、N—H…O和C—H…O相互作用)进一步形成3D超分子结构.研究3个化合物的热稳定性,并探究它们的发光性能.同时,对研究相对较少的H_(3)TZPI有机配体的配位方式进行总结和讨论.
Three coordination polymers were obtained based on the lightly known mixed-donor ligands(the involving m-benzenedi-carboxylate and tetrazole subunits provide O-/N-coordination sites,respectively)coordinating with different metal ions:[Eu(TZI)(H_(2)O)_(5))]·2H_(2)O(1),[Tb(TZI)(H_(2)O)_(4)]·5H_(2)O(2),[Cd(H_(2)TZPI)2(H_(2)O)_(4)]·H_(2)O(3).Single crystal X-ray diffraction analysis indicated that compounds 1 and 2 are similar 1D double-stranded structures,while compound 3 is an OD structure through non-covalent interactions(O—H…N,N—H…O and C—H…O interactions)further form to a 3D supramo-lecular structure.The thermogravimetric analysis and luminescence properties were recheached of the three compounds.Meanwhile,the coordination methods of H_(3)TZPI which is rarely used relatively are summarized and discussed.
