| Two Lead(II)-Organic Coordination Polymers Based on N-Acetic-5-oxygen-nicotinic Acid: Syntheses, Structures and Fluorescence Properties | |
| 摘要: 采用水热法合成了2个以N-乙酸基-5-氧烟酸（H2L）为配体的铅金属-有机配位聚合物：[Pb4（μ3-O）2L2]n（1）和[Pb3（μ4-O）2L]n（2）。通过元素分析、红外光谱和X射线单晶衍射进行了结构表征。结构分析表明，聚合物1属单斜晶系，C2/c空间群，其由[Pb4（μ3-O）2]n构成的刚性无机链通过配体L2-连接成三维网络结构。聚合物2属正交晶系，P212121空间群，其三维结构由[Pb3（μ4-O）2]n构成的无机金属链与配体L2-相互连接形成。研究了2的热稳定性及其在室温下的固体荧光性质。 | |

| Abstract: Two new lead coordination polymers, namely,[Pb4(μ3-O)2L2]n (1),[Pb3(μ4-O)2L]n (2) (H2L=N-acetic-5-oxygen-nicotinic acid) have been prepared by the reaction of Pb(NO3)2 with H2L and characterized by elemental analysis, IR and single crystal X-ray diffraction. Polymer 1 crystallizes in the monoclinic C2/c space group, and features[Pb4(μ3-O)2]n rigid inorganic chains, which are further linked by L2- ligands to form a 3D framework. Polymer 2 crystallizes in the orthorhombic P212121 space group, and displays a 3D framework with[Pb3(μ4-O)2]n inorganic chains. The thermodynamic stability and fluorescence properties of 2 were investigated. | |
