In the indane ring system of the title mol-ecule, C(13)H(12)O(4), the hy-droxy-bearing C atom is 0.134 (1) Å out of the plane of the remaining essentially planar atoms (r.m.s. deviation = 0.010 Å). In the crystal, mol-ecules are linked into chains along the b axis by inter-molecular O-H⋯O hydrogen bonds. Additional stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds.
在标题分子C(13)H(12)O(4)的茚满环体系中，带有羟基的C原子偏离其余基本处于平面的原子平面0.134 (1) Å（均方根偏差 = 0.010 Å）。在晶体中，分子通过分子间O—H⋯O氢键沿b轴连接成链。弱分子间C—H⋯O氢键提供了额外的稳定性。
