摘      要：The title compound rac-11-t-butoxy-l,4-dihydro-l,4-methanoanthracene （C19H200, Mr = 264.35） has been synthesized and characterized by FT-IR, 1H NMR, HRMS spectra and single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/n, with a = 13.5240（10）, b = 8.3453（6）, c = 13.9604（9） A,β = 100.0190（10）°. The structure of the title compound comprises a norbornene unit with a t-butoxy g, roup, having a naphthalene ring fused on one side. The naphthalene is essentially planar with a maximum deviation of 0.032（2） A for atom C（3）. In the crystal, inversion-related molecules are linked by pairs of C- H...O hydrogen bonds, forming a cyclic dimer with R2z （16） graph-set motif. The C-H-..~r interactions are also observed, linking the molecules into a continuous two-dimensional framework structure.
