摘要
采用水热法合成了一种新型镉配合物[Cd2(1,4-BDC)(4-pytyp)(H2O)4]·(1,4-BDC)(1,4-BDC为对苯二甲酸;4-pytyp为4′-(4″-吡啶基)-2,2′∶6′,2″-联吡啶),并对该配合物进行X射线单晶结构分析、元素分析及红外光谱表征.单晶结构分析表明,该配合物属三斜晶系,P-1空间群,晶胞参数a=0.992 3(2)nm,b=1.070 3(2)nm,c=1.292 5(3)nm,α=74.50(3)o,β=78.61(3)o,γ=69.18(3)o,是通过氢键和π-π堆积作用形成的3D超分子结构.同时,对该配合物的热稳定性进行了详细的分析.
A cadmium( Ⅱ )complex [Cd2( 1, 4-BDC ) ( 4-pytyp ) (H20)4] ( 1, 4--BDC ) ( 1 ) ( 1, 4--H2BDC=1, 4-benzenedicarboxylic acid; 4-pytyp = 4'- ( 4''-pyridyl ) -2, 2' : 6', 2-terpyridine ) has been synthesized under hydrothermal conditions and was characterized by X-ray diffraction single crystal structure analysis, elemental analysis and IR spectra. The title complex crystallizes in Triclinic P-1 space group with a=0.992 3 ( 2 ) nm, b= 1.070 3 ( 2 ) formed to a 3D rim, c=1.292 5 ( 3 ) nm, a=74.50 ( 3 ) °, β=78.61 ( 3 )°, y=69.18 ( 3 ) o. The complex was supramolecular network linked by π-π stacking thermogravimetric analysis of the complex was analysized in detail. interactions and hydrogen bonds. Meanwhile,
