摘要：

One new conjugated symmetric fulvene ligand L1 and two new unsymmetric fulvene ligands L2 and L3 were synthesized. Five new supramolecular complexes, namely Ag-2(L1)(3)(SO3CF3)(3) (1) (1, monoclinic, P2(1)/c; a = 12.702(3) angstrom, b = 26.118(7) angstrom, c = 13.998(4) angstrom, beta = 96.063(4)degrees, Z = 4), [Ag(L1)]CIO4 (2) (monoclinic, C2/c; a = 17.363(2) angstrom, b = 13.2794(18) angstrom, c = 13.4884(18) angstrom, beta = 100.292(2)degrees, Z = 8), [Ag(L1)(C6H6)SbF6](.)0.5C(6)H(6)(.)H(2)O (3) (monoclinic, P2(1)/c, a = 6.8839(11) angstrom, b = 20.242(3) angstrom, c = 18.934(3) angstrom, beta = 91.994(3)degrees, Z = 4), Ag(L2)(SO3CF3) (4) (triclinic, P1; a = 8.629(3) angstrom, b = 10.915(3) angstrom, c = 11.178(3) angstrom, alpha = 100.978(4)degrees, beta = 91.994(3)degrees, gamma = 105.652(4)degrees, Z = 2), and Ag(L3)(H2O)(SO3CF3) (5) (triclinic, P1; a = 8.914(5) angstrom, b = 10.809(6) angstrom, c = 11.283(6) angstrom, alpha = 69.255(8)degrees, beta = 87.163(9)degrees, gamma = 84.993(8)degrees, Z = 2) were obtained through self-assembly based on these three new fulvene ligands in a benzene/toluene mixed-solvent system. Compounds 1-5 have been fully characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The results indicate that the coordination chemistry of new fulvene ligands is versatile. They can adopt either cis- or trans-conformation to bind soft acid Ag(l) ion through not only the terminal -CN and furan functional groups but also the fulvene carbon atoms into organometallic coordination polymers or discrete complexes, In addition, the luminescent properties of L1-L3 and their Ag(l) complexes were investigated preliminarily in EtOH and solid state.
