In the title compound, C(15)H(13)BrN(2)O(2), he oxime unit adopts an E conformation with respect to the O-H group. A classical intra-molecular O-H⋯N hydrogen bond results in the formation of a six-membered ring. The crystal structure is stabilized by inter-molecular O-H⋯N hydrogen bonds between the hydr-oxy groups and the oxime N atoms. In addition, the crystal structure also features short inter-molecular Br⋯Br short contacts with a distance of 3.8768 (5) Å.
在标题化合物C₁₅H₁₃BrN₂O₂中，肟单元相对于O—H基团呈E构象。一个典型的分子内O—H⋯N氢键导致形成一个六元环。晶体结构通过羟基与肟N原子之间的分子间O—H⋯N氢键得以稳定。此外，晶体结构还具有分子间Br⋯Br短接触，距离为3.8768 (5) Å。
