The crystal structure of the title compound, C 23 H 28 Br 4 O 6 , confirms that it consists of two hexasubstituted aromatic units linked by a central methylene group. The molecule lies on a crystallographic twofold axis that passes through the methylene bridging atom. Examination of the extended str
Dimethoxy-2,3-dimethylbenzene was brominated under radical conditions to give the title compound, C 10 H 11 Br 3 O 4 . The bond lengths and angles are generally within the normal ranges. The crystal packing is stabilized by weak intermolecular C-HÁ Á ÁO and C-HÁ Á ÁBr hydrogen bonds.
In the title compound, C~18~H~29~BrN~4~, both piperazine rings assume a chair conformation. Weak intermolecular C—H...Br interactions result in dimeric associations in the crystal structure. There are no further interactions between neighbouring dimer units.
