以AgNO3·H2O、2-(1H-咪唑-1-甲基)-1H-苯并咪唑(imb)和1,3,5-苯三甲酸(H3btc)为原料,在120℃下通过溶剂热法合成了一个新的配合物[Ag3(Hbtc)(H2btc)(imb)2](1)。并通过元素分析、红外光谱、热分析对配合物1进行了表征。单晶X-射线衍射分析表明,配合物1为三斜晶系,P-1空间群,在256℃以前很稳定。室温固态荧光测试显示,在313 nm激发波长下,配合物1在419 nm具有较强的荧光发射峰。
A new complex with the formula[ Ag3( Hbtc) (H2btc) (imb)2] ( Ⅰ) is synthesized through the reaction of AgN03 ? H20 with 2-( 1H-imidazol-l-methyl)-1H-benzimidazole ( imb) and 1,3,5- benzenetricarboxylic acid ( H3btc) under solvothermal condition at 120 ℃, structurally characterized by elemental analysis, IR spectra and thermogravimetric analysis. Single-crystal X-ray analysisreveals that complex 1 crystallizes in tr ic l in ic space group P -1. There is no obvious weight loss unti l 256 ℃ . Upon the excitation at 313 nm, th e powder X-ray diffraction patterns of complex 1 exhibite intense emission centered at 419 nm in the solid state at room temperature.
