The title compound, C 12 H 14 N 6 , was synthesized via cyclocondensation of 5-amino-1-guanyl-3-phenyl-1,2,4-triazole with acetone. Only one tautomeric form with an H atom at the triazine N atom was observed in the crystal structure. The compound crystallizes with two almost identical molecules in t
The title compound, C 12 H 14 N 6 , was synthesized via cyclocondensation of 5-guanidino-3-phenyl-1,2,4-triazole with acetone. Only one tautomeric form with the NH H atom vicinal to the methyl groups was observed in the crystal structure. The triazine ring adopts a flattened half-boat conformation.
