TL;DR: The title compound, C14H10Br2O, is a biphenyl derivative containing a –CH2—O—CH2– bridge in the 2,2′-position and displays a twisted conformation with the two benzene rings making a dihedral angle of 45.02 (5)°.
Abstract: The title compound, C14H10Br2O, is a biphenyl derivative containing a –CH2—O—CH2– 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 molecule lies on a crystallographic twofold axis of symmetry passing through the O atom and bisecting the 1,1′ C—C bond.

TL;DR: The title compound, C30H26O4, is a dimer of 6,6′-dimethyldibenzo[d,f][1,3]dioxepine linked by formation of a C—C bond in the para position with respect to one O atom.
Abstract: The title compound, C30H26O4, is a dimer of 6,6′-dimethyldibenzo[d,f][1,3]dioxepine linked by formation of a C—C bond in the para position with respect to one O atom. The dimer is arranged around an inversion centre. As is usually observed in related compounds, the dibenzo group is twisted, the two benzene rings making a dihedral angle of 41.56 (9)°. The seven-membered ring exhibits a twisted conformation.
