【摘要】 以乙酰丙酮和1R,2R-环己二胺进行缩合得到N,N′-双(乙酰丙酮)-1R,2R-环己二胺的Schiff碱配体L1,以乙酰丙酮和1S,2S-环己二胺进行缩合得到N,N′-双(乙酰丙酮)-1S,2S-环己二胺的Schiff碱配体L2,然后将L1和L2与AgClO4,AgBF4,AgSbF6进行配位反应,得到了3个配合物[Ag2(L1)(L2)(ClO4)2]n(1),[Ag2(L1)(L2)(BF4)2]n(2)和[Ag2(L1)(L2)(SbF6)2]n(3),并用元素分析,FT-IR和X-射线单晶衍射进行了表征。结果表明,配合物1-3都属于单斜晶系,空间群P21/n,配合物1的中心Ag(Ⅰ)离子采用扭曲四面体的配位构型,配合物2和3的中心Ag(Ⅰ)离子都是近似平面三角形的配位构型。配合物1-3都通过配位作用向空间扩展形成2D网状结构。更多还原

【Abstract】 The Schiff base ligand L1[N,N′-bis(acetylacetone)-1R,2R-cyclohexanediimine]was synthesized from condensation reaction of 1R,2R-diaminocyclohexane with acetylacetone,The Schiff base ligand L2[N,N′-bis(acetylacetone)-1S,2S-cyclohexanediimine]was synthesized from condensation reaction of 1S,2S-diaminocyclohexane with acetylacetone.AgClO4,AgBF4,AgSbF6each react with L1 and L2 to give three complexes[Ag2(L1)(L2)(ClO4)2]n(1),[Ag2(L1)(L2)(BF4)2]n(2)and[Ag2(L1)(L2)(SbF6)2]n(3)and characterized by elemental analysis,FT-IR and single crystal X-ray diffraction. The results of structural analysis indicate that the complex 1-3crystallize in the monoclinic,space group P21/n,The complex 1coordination environment of Ag(Ⅰ)is a distorted tetrahedral geometry. The complex 2and 3coordination environment of Ag(Ⅰ)are an distorted triangular planar geometry. Complexes 1-3through coordination role extend to the space to form a 2Dnetwork structure.更多还原
