title: 1,3-Di-4-pyridylpropane-4,4'-oxy-dibenzoic acid (1/1).
abstract: The hydro-thermal reaction of Cd(NO(3))(2)·4H(2)O, 1,3-di-4-pyridylpropane (BPP) and 4,4'-oxydibenzoic acid (OBA) led to the formation of the title compound, C(13)H(14)N(2)·C(14)H(10)O(5). The asymmetric unit consists of one mol-ecule of OBA and one of BPP. In the OBA mol-ecule, one COOH group is nearly planar with its attached benzene ring [dihedral angle = 0.9 (1)°], while the other COOH group is slightly twisted with a dihedral angle of 10.8 (3)°. The carboxyl groups form strong inter-molecular O-H⋯N hydrogen bonds with N atoms of the pyridine rings in BPP, linking the mol-ecules into zigzag chains.
