Abstract
3-(1-Hydroxyiminoethyl)-1-phenyl-4-hydro-1,2,4-triazin-5,6-dione, has been prepared from the chiral 1-phenyl-3-acetyloxime-5-benzyl-4,5-dihydro-1,2,4-triazin-6-one in the presence of organotin(IV) compounds in methanol solution. It crystallizes as a 1:1 methanol solvate in the monoclinic space group P 2 1 /c with the lattice parameters: a = 1517.6(1), b = 563.64(3), c=1500.34(13) pm and β = 90.35(1)°. The molecules, in which the heterocyclic ring is planar, are dimer via strong oxime-methanol and methanol-dione hydrogen bonds and by additional N-H---O bridges linking the heterocyclic rings.
