6,11-Dihydrodibenz[b,e]oxepin-11-one

Abstract

In the title compound, C14H10O2, the seven-membered oxepine ring adopts a twist-boat conformation with a dihedral angle between the mean planes of the two fused benzene rings of 42.0 (1)°. In the crystal, mol­ecules are linked into chains propagating along the c axis by inter­molecular C—H⋯O hydrogen bonds and the chains are arranged in layers parallel to (100).
