Abstract
The title compound, C(15)H(13)NO(2), crystallizes with four independent mol-ecules (A, B, C and D) in the asymmetric unit. The carbazole units are almost planar [maximum deviations = 0.015 (3) for A, 0.024 (3) for B, 0.026 (3) for C and 0.046 (3) Å for D]. In all four mol-ecules, there is an O-H⋯O hydrogen bond involving the hy-droxy substituent and the carbonyl O atom of the adjacent acetyl group, which forms a six-membered ring. In the crystal, the four independent mol-ecules are linked via N-H⋯O and C-H⋯O inter-actions.
摘要
标题化合物C(15)H(13)NO(2)在不对称单元中以四个独立分子（A、B、C和D）结晶。咔唑单元几乎呈平面状[A的最大偏差为0.015 (3) Å，B为0.024 (3) Å，C为0.026 (3) Å，D为0.046 (3) Å]。在所有四个分子中，存在一个涉及羟基取代基和相邻乙酰基羰基O原子的O-H⋯O氢键，形成一个六元环。在晶体中，四个独立分子通过N-H⋯O和C-H⋯O相互作用相连。
