title: Dimethyl 4,4'-(pyridine-2,6-diyl)dibenzoate.
abstract: The title mol-ecule, C(21)H(17)NO(4), reveals axial symmetry, with the pyridine N atom located on a crystallographic twofold axis. The mol-ecule is dish-shaped, with dihedral angles between the benzene and pyridine rings of 24.643 (1) and 24.797 (1)°, respectively. The -COO plane and the benzene ring are almost coplanar [dihedral angle = 5.286 (1)°].
