title: 4,4'-(Propane-1,3-di-yl)dibenzoic acid.
abstract: The complete molecule of the title compound, C(17)H(16)O(4), is generated by crystallographic twofold symmetry, with the central C atom lying on the rotation axis and a dihedral angle between the benzene rings of 81.9 (2)°. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonding between carboxyl groups, forming one-dimensional supra-molecular chains.
