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

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—H...N hydrogen bonds with N atoms of the pyridine rings in BPP, linking the molecules into zigzag chains.
