摘 要:以氯化镉、烟碱(Nicotine)为原料在N,N-二甲基甲酰胺(DMF)溶液中反应,合成了1个新的一维链状Cd髤配聚物[Cd3(μ-Cl)6(Nicotine)2(DMF)2(H2O)2]n,用红外光谱、粉末X衍射、X-射线单晶衍射和热重分析对配合物进行了表征。X-射线单晶衍射表明,配合物属单斜晶系,空间群P21,晶胞参数:a=0.998 02(19)nm,b=1.836 89(15)nm,c=1.082 6(2)nm,β=95.809(3)°,V=1.974 5(5)nm3,Z=2,μ(Mo Kα)=2.045 mm-1,F(000)=1 044.0,R1=0.049 9,wR2=0.118 8[Ⅰ>2σ(Ⅰ)]。配合物中镉离子位于扭曲的配位八面体中心,相邻镉离子通过2个氯离子桥连形成了一维链结构,Nicotine、DMF、H2O占据配位八面体的剩余配位点,配聚物一维链平行于a轴。室温固态荧光测试显示,配聚物在448.5、573 nm处具有强的荧光发射。A 1D chain Cd(Ⅱ) coordination polymer[Cd3(μ-C1)6(Nicotine)2(DMF)2(H20)2]n (Where Nicotine=(3-[(2S)- 1-methylpyrrolidin-2-yl]pyridine), DMF =N,N-dimethylformamide) has been synthesized in DMF solution with nicotine and CdC12-2.5H20. The crystal structure of the polymer is characterized by single-crystal X-ray diffraction analysis, FTIR, thermogravimetric analysis (TGA) and X-ray powder diffraction (XRPD). The crystalbelongs to monoclinic system, space group P21. The cell parameters are: a=0,998 02(19) nm, b =1.836 89(15) nm, c=1.082 6(2) nm,/3=95.809(3)°, and V=1.974 5(5) nm3, Z=2,μ(Mo Kc~)=2.045 mm-1, F(000)=I 044.0, R,=0.049 9, wR2=0. 118 8 (Ⅰ〉20-(Ⅰ)). Three Cd(Ⅱ) atoms locate in three distorted coordination octahedron respectively. The Cd(Ⅱ) atoms bridged by μ-C1 to form a 1D chain, and Nicotine, DMF, H:O occupying the remaining coordination site of the approximately octahedral. The 1D chain extends in the a direction. The experimental results show that the title complex has good luminescence property and can be used as potential optical materials. CCDC: 819349.
