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
