以Cd2+和[Cr(CN)6]3-为建筑基元通过自组装合成普鲁士蓝类配位聚合物KCd[Cr(CN)6]·H2O(1·H2O),并用红外光谱、元素分析、单晶X射线衍射、粉末X射线衍射、热重分析和氮气吸附脱附等手段对其进行了表征.配位聚合物1·H2O属于面心立方晶系,空间群Fm-3m,晶胞参数:a=b=c=1.09059mn,α=β=γ=90°.配位聚合物1·H2O是由K+,Cd2+,[Cr(CN)6]3-离子和一个结晶水分子组成的三维多孔结构.热重分析结果表明失水样品1的骨架结构在120～200℃之间保持稳定.氮气吸附脱附研究表明:失水样品1具有683.6m2·g-1的比表面积,氮气最大吸附量为8.83mmol·g-1.
The Prussian blue coordination polymer KCd [Cr (CN) 6] · H2O (1 · H2O) was synthesized by self-assembly using Cd2 + and [Cr (CN) 6] 3- as building elements. Single crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis and nitrogen adsorption and desorption etc. Coordination polymer 1 · H2O belongs to the face-centered cubic system, space group Fm-3m, unit cell parameters : a = b = c = 1.09059mn, α = β = γ = 90 ° Coordination polymer 1 · H2O is a three-dimensional Porous structure.The thermogravimetric analysis showed that the skeleton structure of dehydrated sample 1 remained stable between 120 and 200 ° C. Nitrogen adsorption and desorption studies showed that dehydrated sample 1 had a specific surface area of 683.6 m 2 · g -1 and the maximum adsorption of nitrogen The amount was 8.83 mmol · g -1.
