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.
