【摘要】 采用水热法合成了2个铁的过渡金属配位聚合物[Fe(Medpq)(BDC)H2O]n(1)和{[Fe(Medpq)(QUI)H2O]·2H2O}n(2)(Medpq=2-methyldipyrido[3,2-f:2′,3′-h]quinoxaline;H2BDC=terephthalic acid;H2QUI=2,3-pyridinedicarboxylic acid),并对其进行了元素分析、红外光谱和热重表征,并用X射线单晶衍射测定结构。2个配位聚合物中的中心铁(Ⅱ)离子,都呈现一个稍微扭曲的八面体几何构型。更多还原

【Abstract】 Two iron(Ⅱ) coordination polymers [Fe(Medpq)(BDC)H2O]n(1) and {[Fe(Medpq)(QUI)H2O]·2H2O}n(2)(H2BDC =terephthalic acid, H2 QUI =2,3-pyridinedicarboxylic acid and Medpq =2-methyldipyrido [3,2-f:2′,3 ′-h]quinoxaline) were prepared by hydrothermal method. They were characterized by elemental analysis, IR and thermogravimetric analysis, and their structures were determined by single-crystal X-ray diffraction. The Fe (Ⅱ) ions of the two coordination polymers all assumed a slightly distorted octahedral geometry.更多还原
