The title compound, C9H7BrO2, displays a trans configuration with respect to the C=C double bond and is essentially planar [maximum deviation from the least-squares plane through all non-H atoms = 0.056 (4) Å]. The vinyl-aldehyde group adopts an extended conformation wih a C-C-C-C torsion angle of 179.7 (4)°. In the crystal, mol-ecules are linked by classical O-H⋯O and weak C-H⋯O hydrogen bonds into a three-dimensional supra-molecular network.
标题化合物C9H7BrO2相对于C=C双键呈反式构型，且基本为平面结构[所有非H原子与最小二乘平面的最大偏差 = 0.056(4) Å]。乙烯基醛基团采取伸展构象，C-C-C-C扭转角为179.7(4)°。在晶体中，分子通过经典的O-H⋯O和弱的C-H⋯O氢键连接成三维超分子网络。
