Tautomeric structures of 3-amino[1,2,4]triazolo[4,3-a]pyrimidin-5-one in the gas phase and aqueous solution were investigated using DFT B3LYP/6-311++(2d,2p) calculations. Intramolecular hydrogen bond parameters were calculated and their influence on the stability of the tautomeric forms evaluated using the quantum theory of "atoms in molecules".
