| 摘要: 溶剂热条件下采用Cd(NO3)2·4H2O，5-甲基吡嗪-2-甲酸和4，4-联吡啶作为反应物合成出一个新的具有二维层状结构的镉金属配位聚合物 [Cd(mpac)(4，4-bpy)(OH)]n(1)，并分别用元素分析，红外光谱，热重分析和X-射线单晶衍射表征该结构。晶体结构分析结果表明：5-甲基吡嗪-2-甲酸将Cd(Ⅱ)离子连接成一维链，这些链进一步被4，4-联吡啶连接成二维层状结构。在二维层状结构中存在大小为0.24×1.16 nm2的一维通道。荧光谱图表明常温固态下配合物1发射蓝色荧光。 |

| Abstract: A 2D cadmium coordination polymer, [Cd(mpac)(4, 4-bpy)(OH)]n(1) (Hmpac=5-methyl-2-pyrazinecarboxylic acid, 4,4-bpy=4,4-bipyridine) has been synthesized by solvothermal method and characterized by elemental analysis, IR, TGA and single-crystal X-ray diffraction. The mpac ligands link the Cd(Ⅱ) atoms to form an infinite Cd-carboxylate chain. These chains are further bridged by 4,4-bpy ligands, forming a new two-dimensional layered network. Interestingly, there are small channels of 0.24×1.16 nm2 within the 2D individual layers along the b-axis. Furthermore, the luminescent property of complex 1 was investigated at room temperature.
