二维层状聚合物{[Mn_3(btc)(Hbtc)(H_2btc)(H_2O)_6]·6H_2O}_n的合成

Synthesis of the Two-Dimensional Hybrid {[Mn_3(btc)(Hbtc)(H_2btc)(H_2O)_6]·6H_2O}_n

利用蒸气扩散法合成了1,3,5-苯三酸与锰(Ⅱ)的二维层状聚合物{[Mn3(btc)(Hbtc)(H2btc)(H2O)6].6H2O}n(H3btc=1,3,5-苯三酸)。通过X射线单晶衍射、元素分析和红外光谱对其结构进行了表征。中心离子Mn(Ⅱ)处于扭曲的八面体配位环境中,来自btc同一个羧基的两个氧原子,和分别来自Hbtc、H2btc的两个氧原子占据赤道平面,两个配位水的氧原子占据轴向位置。

Two-dimensional network complex {[-Mn3 （btc） （Hbtc） （H2btc） （H2O）] · 6H2O}n （H3btc = benzene-l, 3, 5-tricarboxylic acid） was synthesized by vapor diffusion method and characterized by elemental analysis and IR. The structure was determined by single crystal X-ray diffraction analysis. The Mn （ Ⅱ ） ion displays octahedral coordination environment with two oxygen atoms from one carboxyl of btc and two oxygen atoms from Hbtc and Hzbtc in the equatorial plane, while two oxygen atoms from two terminal H2O molecules occupy the axial positions.
