摘要:
该文以咪唑衍生物2-(1H-咪唑-1-甲基)-6-甲基-1H-苯并咪唑(immb)和芳香二羧酸间苯二甲酸(H2bdic)为配体,在120 ℃的水热条件下通过与CdCl2·2.5H2O的自组装,成功得到了一个新的配位化合物{[Cd(immb)(bdic)(H2O)]·H2O}n(1)。通过元素分析、傅里叶红外光谱分析、单晶结构分析、粉末衍射图谱分析、热稳定性分析、激发及荧光光谱分析对目标配合物进行了表征。该配合物属于三斜晶系,空间群为P-1。Cd(Ⅱ)离子均处于七配位环境中,并且同时被immb配体和bdic2-阴离子桥联形成二维网状结构,层与层之间又借助于分子间的氢键彼此连接形成三维超分子结构。室温下,固态配合物1在269 nm下激发,在331 nm处出现较强荧光发射峰。
Abstract:
A novel Cd(Ⅱ)complex,namely {[Cd(immb)(bdic)(H2O)]·H2O}n(1),is prepared by the hydrothermal reaction of CdCl2·2.5H2O with 2-(1H-imidazol-1-methyl)-6-methyl-1H-benzimidazole(immb)and 1,3-benzenedicarboxylic acid(H2bdic)at 120 ℃. It is characterized by the elemental analysis,infrared spectroscopy(IR),single crystal structure analysis,powder diffraction pattern analysis,thermal stability analysis,fluorescence excitation and emission spectra analysis. Complex(1)belongs to triclinic system,space group P-1. Cd(Ⅱ)ion is seven-coordinated and bridged by immb ligands and bdic2- anions leading to a two-dimensional(2D)network,which are further extended to three-dimensional(3D)supramolecular structure by hydrogen bonds. Upon excitation at 269 nm,the title complex exhibits intense emission at 331 nm at room temperature for the solid state.
