title: 3,9-Dibromo-5,7-dihydro-dibenzo[c,e]oxepine.
abstract: The title compound, C(14)H(10)Br(2)O, is a biphenyl derivative containing a -CH(2)-O-CH(2)- bridge in the 2,2'-position. The compound displays a twisted conformation with the two benzene rings making a dihedral angle of 45.02 (5)°, while the central seven-membered ring is in a boat conformation. The mol-ecule lies on a crystallographic twofold axis of symmetry passing through the O atom and bis-ecting the 1,1' C-C bond.
