1,3-Di-4-pyridylpropane-4,4'-oxydibenzoic acid (1/1)

G. Li, C. Salim and H. Hinode

Abstract: The hydrothermal reaction of Cd(NO₃)₂·4H₂O, 1,3-di-4-pyridylpropane (BPP) and 4,4'-oxydibenzoic acid (OBA) led to the formation of the title compound, C₁₃H₁₄N₂·C₁₄H₁₀O₅. The asymmetric unit consists of one molecule of OBA and one of BPP. In the OBA molecule, 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 intermolecular O-HN hydrogen bonds with N atoms of the pyridine rings in BPP, linking the molecules into zigzag chains.
