The title compound, C(8)H(10)N(2)O(2), crystallizes as two independent mol-ecules linked by N-H⋯N and N-H⋯O hydrogen bonds into a linear chain running along the a axis of the monoclinic unit cell. The intra- and inter-molecular hydrogen bonds are described as a two-ring R(2) (2)(10) motif. The six-membered R(1) (1)(6) rings formed by the intra-molecular inter-actions are almost planar (r.m.s. deviations 0.06 and 0.08 Å). In one mol-ecule, the aromatic and hydrogen-bonded rings are oriented at 4.8 (2)°, whereas in the other mol-ecule these rings are oriented at 6.1 (4)°.
标题化合物C(8)H(10)N(2)O(2)以两个独立分子的形式结晶，这些分子通过N-H⋯N和N-H⋯O氢键连接成一条沿单斜晶胞a轴延伸的线性链。分子内和分子间的氢键被描述为一种双环R(2) (2)(10)基序。由分子内相互作用形成的六元R(1) (1)(6)环几乎是平面的（均方根偏差为0.06和0.08 Å）。在一个分子中，芳香环和氢键环的取向为4.8 (2)°，而在另一个分子中，这些环的取向为6.1 (4)°。
