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。
Two supramolecular compounds [Cd (L1) (HL1) I] (1) were synthesized by hydrothermal method using 4-imidazolyl benzoic acid (HL1) ) And [Co2 (L1) 4 (H2O) 8] (2) were synthesized and characterized by elemental analysis, IR, TG, powder diffraction and X-ray single crystal diffraction. The results of crystal structure analysis show that the complex 1 belongs to the monoclinic space group P21 / c and the L1-ligand connects the Cd (Ⅱ) ions into a one-dimensional chain. The one-dimensional chains are connected by hydrogen bonds into triple- Structure. In the asymmetric structure unit of complex 2, there are three different kinds of metal Co (Ⅱ) central mononuclear molecules, which are connected to each other by abundant hydrogen bonds to form a three-dimensional polymer. At the same time, the solid fluorescence properties of complex 1 at room temperature and the adsorption properties of complex 2 on the gas were studied.
