| 摘要: 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(H2L)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)(H2O)]n(1)、[Co (L)(phen)(H2O)]n(2)、[Cu (L)(phen)(H2O)]n(3)、[Zn2(L)2(phen)2(H2O)]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。 | |

| Abstract: Under solvothermal conditions, six new coordination polymers (CPs) [Mn(L) (phen) (H2O)]n (1), [Co(L) (phen)(H2O)]n (2), [Cu(L)(phen)(H2O)]n (3), [Zn2(L)2(phen)2(H2O)]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 (H2L) 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 interactions 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. | |
