低热固相合成类金刚石型配位聚合物Zn(INA)_2

Synthesis of a Diamond-Like Coordination Polymer,Zn(INA)_2 by Solid State Reaction at Lower Heating Temperature

用低热固相合成法制备了配位聚合物Zn(INA)2(HINA=异烟酸),并用X射线粉末衍射,SEM等方法对产物进行了表征。该合成方法在近室温下进行,不需溶剂的参与,反应迅速,且产率接近100%,是一种高效简便的绿色合成方法。制得的配位聚合物Zn(INA)2具有四面体结构的四配位Zn2+中心,形成了类似金刚石结构的三维框架,并具有较好的热稳定性。

A coordination polymer, Zn（INA）2 （HINA-Isonicotinic acid） was prepared by a solid state reaction of Zn（CH3COO）2·4H2O and HINA at lower heating temperature. The mixture was grinded in a agate mortar for 30 minutes and heated under 80 ℃ for 2 hours. The method is convenient and environment-friendly, which gives a nearly 100% yield. The product was characterized by X-ray powder diffraction method. The Zn^2＋ centers are fourcoordinate and have a tetrahedal geometry and extend three dimensionally to form a diamondoid network, and the complex has a high thermal stability.
