摘　　要：Under solvothermal conditions,six new coordination polymers(CPs)[Mn(L)(phen)(H_(2)O)]_(n)(1),[Co(L)(phen)(H_(2)O)]_(n)(2),[Cu(L)(phen)(H_(2)O)]_(n)(3),[Zn_(2)(L)_(2)(phen)2(H_(2)O)]_(n)(4),[Zn(L)(phen)]_(n)(5),and[Cd(L)(phen)2]_(n)(6)were synthesized by reactions of dicarboxylate ligand 2,2'-(1,2-phenylenebis(methylene))bis(sulfanediyl)dinobutyric acid(H_(2)L)and 1,10-phenanthroline(phen)with the corresponding metal salts.Complexes 1-6 have been structurally characterized by single-crystal X-ray diffraction analyses,elemental analysis,IR,thermogravimetric analysis,and powder X-ray diffraction.The structures of 1-6 are 1D chains,which are further connected by hydrogen bonding interac-tions to form 3D supramolecular structures.Among them,1 and 2 are isomorphic with L2-of syn-conformation,while L2-shows anti-conformation in 3-6.In addition,the solid-state photoluminescence property of 4-6 was investigated.在溶剂热条件下,柔性二羧酸配体2,2'-(1,2-亚苯基双(亚甲基))双(硫二基)二尼古丁酸(H_(2)L)和1,10-菲咯啉(phen)与不同金属盐反应合成了6个新颖的配位聚合物:[Mn(L)(phen)(H_(2)O)]_(n)(1)、[Co(L)(phen)(H_(2)O)]_(n)(2)、[Cu(L)(phen)(H_(2)O)]_(n)(3)、[Zn_(2)(L)_(2)(phen)2(H_(2)O)]_(n)(4)、[Zn(L)(phen)]_(n)(5)和[Cd(L)(phen)2]_(n)(6)。对配合物1~6进行了单晶X射线衍射、元素分析、红外光谱、热重分析、粉末X射线衍射等测试和表征。1~6的单晶结构为不同的一维链,且能通过氢键作用链接形成三维超分子结构。其中1和2同构且L2-呈现顺式构象,3~6中L2-呈现反式构象。此外,研究了配合物4~6的荧光性质。
