| Two Coordination Polymers Based on Carboxylate Ligands and Fe(Ⅱ): Preparation, Structural Characterization and Properties |
|
| 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。 |

| Abstract: Two iron(Ⅱ) coordination polymers [Fe(Medpq)(BDC)H2O]n (1) and {[Fe(Medpq)(QUI)H2O]·2H2O}n (2) (H2BDC=terephthalic acid, H2QUI=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. CCDC: 1436495, 1; 1436494, 2. |
