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
A new di-Schiff base ligand, 1,2-bis(3′-pyridylmethyleneamino)ethane(L), was designed and its Ag(Ⅰ) complex[Ag 2(L) 2](CF 3SO 3) 2 was synthesized.

The crystal structure analysis indicates that the complex crystallizes in monoclinic system, space group of C2/c with a=3.770 4(2) nm, b=0.797 90(10) nm, c=2.471 3(2) nm, β=101.840(10)°, V=7.276 5(12) nm 3, Z=8, D c=1.808 g/cm 3, \{F(000)=\}3 936, R=0.058 3, wR=0.076 6, (Δρ) max=0.657×10 3 e/nm 3,(Δρ) min=-0.562×10 3 \{e/nm 3\}. It is interesting that one L ligand coordinates to three Ag(Ⅰ) atoms using four N atoms, while another L ligand connects two Ag(Ⅰ) atoms with three of four N atoms and one N atom keeps free of coordination.展开更多
