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。
The two-dimensional layered polymer {[Mn3 (btc) (Hbtc) (H2btc) (H2O) 6] .6H2O} n (H3btc = Trimesic acid). Its structure was characterized by X-ray single crystal diffraction, elemental analysis and infrared spectroscopy. The central ion Mn (Ⅱ) is in a distorted octahedral coordination environment with two oxygen atoms from the same carboxy group of btc and two oxygen atoms from Hbtc and H2btc respectively occupy the equatorial plane. The oxygen atoms of the two coordination water Occupy axial position.
