Abstract

 Some new Schiff bases, (Z)-4-amino-3-((E)-(R-methoxybenzylidene) hydrazono)-6-methyl-3,4-dihydro-1, 2, 4-triazin-5 (2H)-one (R=2 (L2), R=3 (L3) and R=4 (L4)), were synthesized by the condensation reactions of 4-amino-3-hydrazinyl-6-methyl-1,2,4-triazin-5(4H)-one (L1) and corresponding methoxybenzaldehyde in a molar ratio 1:1.5 in high yields. The reaction of L2 and L4 with an excess amount of the corresponding aldehydes gave the unsymmetrical bis-Schiff bases (E)-3-((E)-(R-methoxybenzylidene)hydrazono)-4-((E)-R-methoxybenzylideneamino)-6-methyl-3,4-dihydro-1,2,4-triazin-5(2H)-one (R=2 (L22) and R=4 (L44)), respectively. Furthermore, the reaction of L2–L4 with silver(I) nitrate in a molar ratio 2:1 led to the silver(I)-complexes with the general formula [Ag(Lx)2]NO3 (Lx=L2 (2), L3 (3) and L4 (4)). All synthesized Schiff base compounds and complexes were characterized by a combination of IR-, 1H-NMR spectroscopy, mass spectrometry and elemental analyses. In addition, the structures of L2, L4.CH3CN, L22.CH3OH and L44.CH3OH and complexes 2 and 4 were determined by X-ray diffraction studies.
