| 摘要: 以含4-咪唑和羧酸基团的双功能基团4-咪唑基苯甲酸(HL1)为配体,用水热法合成了2个超分子化合物[Cd(L1)(HL1)I](1)和[Co2(L1)4(H2O)8](2),并进行了元素分析、红外、热重、粉末衍射及X-射线单晶衍射等表征.晶体结构解析结果表明:配合物1属于单斜晶系,P21/c空间群,L1-配体连接Cd(Ⅱ)离子成一维链,这些一维链通过氢键连接成三重贯穿的α-Po结构的超分子聚合物;配合物2不对称结构单元中,存在3种不同的金属Co(Ⅱ)中心单核分子,这些相互独立的分子单元通过丰富的氢键连接成三维的聚合物.同时,对配合物1室温下的固体荧光性质和配合物2对气体的吸附性能进行了研究. | |

| Abstract: Two complexes, [Cd(L1)(HL1)I] (1, HL1=4-(1H-imidazol-4-yl)benzoic acid) and [Co2(L1)4(H2O)8] (2), have been hydrothermally prepared and characterized by single-crystal X-ray diffraction, elemental analysis, IRspectroscopy, photoluminescence property, TGand PXRD. Complex 1 crystallizes in monoclinic, space group P21/c. The L1-ligands link Cd(Ⅱ) atoms to form one-dimensional chains, which are further bridged to form a three-dimensional three-fold interpenetrating α-Po supramolecular polymer by hydrogen bonds. X-ray diffraction analysis revealed three different kinds of Co(Ⅱ) centre mononuclear molecules in the asymmetric unit. The independent mononuclear units are bridged to form a three-dimensional supramolecular polymer by extensive hydrogen bonds interactions. Solid state luminescent property of 1 and sorption property of 2 have been investigated. CCDC: 983657, 1; 1027672, 2. | |
