The title compound, C<sub>26</sub>H<sub>20</sub>N<sub>2</sub>O<sub>5</sub>, is a rearrangement product of an <i>o</i>-pyridinyl anthracenyl isoxazole ester. It features a bicyclic acetal structure, which has two extended almost co-planar ring systems, which subtend a fold angle of 102.17 (5)°. In the crystal, the mol-ecules are closely knitted together through C-H⋯N and C-H⋯O hydrogen bonds and form chains of alternating enanti-omers propagating along the <i>c-</i>axis direction. ...[more]
