The complexes were characterized by elemental analysis, IR and 1H NMR measurements. Bioactivity tests showed that the complexes inhibited the cucumber mosaic virus. Among them the best effective was glycine salicylaldehyde Schiffbase Ag(Ⅰ), which gave the effective level up to 74.7% towards CMV in dosage of 400 mg/L(in case of phaseolus vulgarisl inoculation).展开更多
The title compound, a novel Ag（Ⅰ） carboxyarylphosphonate [Ag（H2BCP）（4,4＇- bipy）]·2H2O （H3BCP = p-H2O3PCH2C6H4COOH, 4,4＇-bipy = 4,4＇-bipyridine）, was synthesized by a hydrothermal reaction and characte...The title compound, a novel Ag（Ⅰ） carboxyarylphosphonate [Ag（H2BCP）（4,4＇- bipy）]·2H2O （H3BCP = p-H2O3PCH2C6H4COOH, 4,4＇-bipy = 4,4＇-bipyridine）, was synthesized by a hydrothermal reaction and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. It belongs to monoclinic system, space group P21/c with a = 5.7038（11）, b = 22.397（4）, c = 5.602（4） , β = 106.26（3）°, V = 1913.4（7） 3, Z = 4, C18H20N2O7PAg, Mr = 515.20, Dc = 1.788 g/cm3, μ = 1.182 mm–1, F（000） = 1040, the final R = 0.0404 and wR = 0.1216 for 4178 observed reflections with I 2σ（Ⅰ）. In the structure, the Ag（Ⅰ） cations are bridged by 4,4＇-bipy to give rise to 1D chains running along the b axis. These chains are linked further by the interactions of O （from BCP ligands） and Ag atoms to yield 2D layers. Hydrogen bonding interactions and weak π-π stacking interactions between 4,4＇-bipy rings assemble such adjacent layers to generate a 3D supramolecular architecture.展开更多
