In the title compound, C16H12O4, the substituent benzene ring and meth-oxy group are twisted relative to the 4H-chromene skeleton by 24.1 (1) and 61.3 (1)°, respectively. In the crystal, mol-ecules are connected by classical O-H⋯O and weak C-H⋯O hydrogen bonds, forming chains parallel to [201]. The 4H-chromene ring systems of adjacent mol-ecules are either parallel or inclined at an angle of 28.9 (1)°.
在标题化合物C₁₆H₁₂O₄中，取代苯环和甲氧基相对于4H-色烯骨架分别扭转了24.1 (1)°和61.3 (1)°。在晶体中，分子通过经典的O-H⋯O和弱的C-H⋯O氢键相连，形成平行于[201]的链。相邻分子的4H-色烯环系统要么平行，要么以28.9 (1)°的角度倾斜。
