In the title compound, CHClNO, one quinoline ring system is essentially planar and the other is slightly bent. An intra-molecular O-H⋯N hydrogen bond involving the hy-droxy group and a pyridine N atom forms an (5) ring motif. In the crystal, two mol-ecules are associated into an inversion dimer with two (7) ring motifs through inter-molecular O-H⋯N and O-H⋯O hydrogen bonds. The dimers are further linked by an inter-molecular C-H⋯O hydrogen bond and four C-H⋯π inter-actions, forming a two-dimensional network parallel to (001).
在标题化合物CHClNO中，一个喹啉环系基本呈平面状，另一个则稍有弯曲。涉及羟基和吡啶N原子的分子内O—H⋯N氢键形成了一个（5）环模式。在晶体中，两个分子通过分子间O—H⋯N和O—H⋯O氢键缔合形成一个具有两个（7）环模式的反演二聚体。二聚体通过分子间C—H⋯O氢键和四个C—H⋯π相互作用进一步连接，形成一个平行于（001）的二维网络。
