| Abstract: 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 Lwas 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, elemental 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=0.9902(11) nm, b=2.181(2) nm, c=1.0122(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=0.0642, and wR2=0.1174 (observed reflections with I >2σ(I)). Complex 1 crystallized in the monoclinic system, space group P21/n, with the following crystallographic data: a=1.27057(11) nm, b=1.45644(13) nm, c=1.66985(14) nm, β=105.643(3)°, V=2.9756(4) nm 3, Z=4, Dc=1.918 g·cm-3, Mr=859.39, μ=1.907 mm-1, F(000)=1664, R1=0.0417, and wR2=0.1032 (observed reflections with I >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. CCDC:1008802, L; 1008804, 1. |
