The title compound [CCDC 199359], C₁₆H₂0N₅ crystallized in Monoclinic system with the space group C2/c. The unit cell parameters are: a = 16.554(6), b = 12.145(4), c = 16.221(5)Å and β = 102.67(1)º. The molecular structure is stabilized by an intramolecular C-H...N type hydrogen bond and the molecular packing by the intermolecular C-H...N and N-H...N type hydrogen bonds.
