The title compound, C(10)H(10)N(2)O, crystallizes with two independent mol-ecules in the asymmetric unit, having closely comparable geometries. The dihedral angles between the 1H-pyrazole and benzene rings in the two mol-ecules are 39.57 (14) and 41.95 (13)°. The two mol-ecules are each connected to neighbouring mol-ecules by pairs of inter-molecular O-H⋯N hydrogen bonds, forming dimers with R(2) (2)(8) ring motifs. These dimers are further linked into R(4) (4)(10) ring motifs by inter-molecular N-H⋯O hydrogen bonds, forming chains along [101]. The crystal structure is further stabilized by a C-H⋯π inter-action.
标题化合物C(10)H(10)N(2)O在不对称单元中以两个独立分子结晶，其几何结构相近。两个分子中1H-吡唑环与苯环之间的二面角分别为39.57 (14)°和41.95 (13)°。两个分子均通过分子间O-H⋯N氢键对与相邻分子相连，形成具有R(2) (2)(8)环模式的二聚体。这些二聚体通过分子间N-H⋯O氢键进一步连接成R(4) (4)(10)环模式，沿[101]方向形成链状结构。晶体结构通过C-H⋯π相互作用进一步稳定。
