5-Bromo-1-(4-bromophenyl)isatin

Abstract

In the title compound [systematic name: 5-bromo-1-(4-bromophenyl)-2,3-dihydro-1H-indole-2,3-dione], C14H7Br2NO2, all of the atoms except the C—H groups in the bromobenzene ring lie on a (010) crystallographic mirror plane, with the benzene ring completed by reflection. The dihedral angle between the ring systems is constrained to be 90° by symmetry. In the crystal, molecules are linked by weak C—H...Br interactions in the [001] direction and paired very weak C—H...O interactions to the same acceptor in the [100] direction, generating (010) sheets. Possible extremely weak π–π stacking occurs between the layers.
