Redetermined structure of 4-(benzyloxy)benzoic acid
The molecules of the title compound form acid–acid homodimers in the crystal structure.
In the title compound, C14H14O3, the dihedral angle between the aromatic rings is 39.76 (9)°. In the crystal, the molecules associate to form centrosymmetric acid–acid dimers linked by pairwise O—H⋯O hydrogen bonds. The precision of the geometric parameters in the present single-crystal study is about an order of magnitude better than the previous powder diffraction study [Chattopadhyay et al. (2013#). CrystEngComm, 15, 1077–1085].
