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。The Schiff base ligand L1 [-N, N'-bis(acetylacetone)-lR, 2R-cyclohexanediimine-] was synthe- sized from condensation reaction of 1R, 2R-diaminocyclohexane with acetylacetone, The Schiff base ligand L2 IN, N'-bis(acetylacetone)-lS, 2S-cyclohexanediimine] was synthesized from condensation re- action of 1S,2S-diaminocyclohexane with acetylacetone. AgC104, AgBF4, AgSbF6 each react with L1 and L2 to give three complexes[-Ag2 ( L1 ) ( L2 ) ( C104 ) 2 ]n (1), I- Ag2 ( L1 ) ( Lz ) ( BF4 ) 2 ]n (2) and [ Age (L1) (L2) (SbF6)2-]. (3) and characterized by elemental analysis, FT-IR and single crystal X-ray dif- fraction. The results of structural analysis indicate that the complex 1 -3 crystallize in the monoclinic, space group P21/., The complex 1 coordination environment of Ag( I ) is a distorted tetrahedral ge- ometry. The complex 2 and 3 coordination environment of Ag( I ) are an distorted triangular planar geometry. Complexes 1 -3 through coordination role extend to the space to form a 2D network structure.
