摘要
在400K温度下,以Mn(CH_3COO)_2,KI和Ag I为原料,将其按化学计量比进行混合,在N,N-二甲基甲酰胺(DMF)、二乙烯三胺(dien)、HI和蒸馏水混合溶剂的条件下,通过溶剂热合成方法反应得到了一个新的多元银碘化合物[Mn(dien)_2]_2Ag_2I_6.通过元素分析和X-射线单晶衍射仪对此化合物进行结构表征,该化合物属于单斜晶系,空间群为P21/c.其晶体结构由二聚阴离子[Ag2I6]4-和过渡金属配合物[Mn(dien)2]2+阳离子组成,两种结构单元通过氢键相互连接形成三维网状结构.
A new transition metal complex directed iodoargentate, [Mn（dien）2]2Ag2I6（dien=diethylenetriamine）, has been synthesized by solvothermal reacting of Mn（CH3COO）2·4H2O, KI and Ag I in a stoichiometric ratio in DMF and dien solution at 400 K. The structure was characterized by elemental analysis and single-crystal X-ray diffraction. The compound crystallizes in the triclinic space group P21/c. The structure consists of [Ag2I6]4- anion and transition metal complex [Mn（dien）2]2＋ cation. These two types of units are interlinked via various hydrogenbonding interactions to from a three-dimensional（3D） network.
