摘要 用1,3-双(2-甲酰基苯氧基)-2-丙醇和丙二腈进行反应得到1,3-双(2-(2,2-二氰乙烯基)苯氧基)-2-丙醇配体L,然后将配体与Ag Sb F6进行配位反应,得到配合物[Ag LSb F6]n·n CHCl3(1),并用元素分析,FTIR和X-射线单晶衍射进行了表征。结果表明,配体L属于单斜晶系,空间群P21/n,晶体学参数:a=0.990 2(11)nm,b=2.181(2)nm,c=1.012 2(11)nm,β=109.374(10)°,V=2.062(4)nm3,Z=4,Dc=1.277 g·cm-3,Mr=396.40,μ=0.087 mm-1,F(000)=824,R1=0.064 2,w R2=0.117 4(I>2σ(I))。配合物1属于单斜晶系,空间群P21/n,晶体学参数:a=1.270 57(11)nm,b=1.456 44(13)nm,c=1.669 85(14)nm,β=105.643(3)°,V=2.975 6(4)nm 3,Z=4,Dc=1.918 g·cm-3,Mr=859.39,μ=1.907 mm-1,F(000)=1 664,R1=0.0417,w R2=0.1 032(I>2σ(I))。在配合物1中,配体L表现为四齿配体分别与4个银(Ⅰ)离子配位,同时,每一个银(Ⅰ)离子与4个相邻配体配位形成2D层状结构。同时,研究了配体和配合物的固体荧光性质。 1,3-bis (2-formylphenoxy)-2-propanol underwent an ammonium acetate-catalyzed condensation reaction with dicyanomethane to afford the ligand 1,3-bis(2-(2,2-dicyanovinyl)phenoxy)-2-propanol (L). Further, the ligand L was made to react with hexafluoroantimonate(AgSbF6) which resulted in the formation of coordination polymer [AgLSbF6]n·nCHCl3 (1). Complex 1 so-obtained was characterized by Fourier transform infrared spectroscopy, ele- mental analysis, and single crystal X-ray diffraction. The results of X-ray crystallographic analysis indicated that the ligand L crystallized in the monoclinic system, space group P21/n, with the following crystal cell parameters: a=0.990 2(11) nm, b=2.181(2) nm, c=1.012 2(11) nm, β=109.374(10)°, V=2.062(4) nm^3, Z=4, Dc=1.277 g·cm^-3, Mr=396.40,μ=0.087 mm^-1, F(000)=824, R1=0.064 2, and wR2=0.1174 (observed reflections with 1〉2σ(Ⅰ)). Complex 1 crystallized in the monoclinic system, space group P21/n, with the following crystallographic data: a= 1.270 57(11) nm, b=1.456 44(13) nm, c=1.669 85(14) nm, 13=105.643(3)°, V=2.975 6(4) nm^3, Z=4, Do=1.918 g·cm^-3, Mr=859.39,μ=1.907 mm^-1, F(000)=1664, R1=0.041 7, and wR2=0.103 2 (observed reflections with 1〉2σ(Ⅰ)). In the crystal structure, each ligand L acted as a tetradentate ligand coordinating four Ag(I) centers, and each Ag (I) was connected to four ligands L, forming two-dimensional layered structure. Moreover, the fluorescent properties of ligand L and complex 1 were investigated in the solid state at room temperature.
