title: Ethyl trans-12-(pyridin-4-yl)-9,10-ethano-anthracene-11-carboxyl-ate.
abstract: In the title compound, C24H21NO2, the residues at the central ethyl-ene bridge are trans to each other. The dihedral angles between the pyridine and benzene rings are 67.09 (6) and 61.41 (5)°. In the crystal, centrosymmetrically related mol-ecules are linked into dimers by pairs of C-H⋯O hydrogen bonds.
