The title compound, C(15)H(14)O(3), has been found to crystallize as a new triclinic polymorph. The asymmetric unit of the present structure, as in the previously reported monoclinic structure [Norment & Karle (1962 ▶). Acta Cryst. 15, 873-878], contains two independent mol-ecules, which differ slightly in the orientations of the two benzene rings. The crystal packing of the triclinic polymorph is stabilized by inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
已发现标题化合物C(15)H(14)O(3)以一种新的三斜晶型多晶型物形式结晶。与先前报道的单斜晶型结构[诺门特和卡尔（1962年▶）。《晶体学报》，15，873 - 878]一样，当前结构的不对称单元包含两个独立分子，这两个分子的两个苯环取向略有不同。三斜晶型多晶型物的晶体堆积通过分子间C - H⋯O氢键和C - H⋯π相互作用得以稳定。
