Abstract

Molecules of the title compound, C13H16N4O2, are linked by one N-H...O hydrogen bond [H...O = 2.47 A, N...O = 3.326 (2) A and N-H...O = 166 degrees ] and one N-H...N hydrogen bond [H...N = 2.19 A, N...N = 3.063 (2) A and N-H...N = 173 degrees ] into sheets containing alternating R2(2)(20) and R6(6)(32) rings, both types of which are centrosymmetric.
