2,2,6,6-Tetrabromo-3,4,4,5-tetramethoxycyclohexanone

Abstract

In the title compound, C10H14Br4O5, synthesized from the methoxy Schiff base N-(pyridin-2-ylmethyl)methoxyaniline and molecular bromine, the cyclohexanone ring has a chair conformation with one of the four methoxy groups equatorially orientated with respect to the carbonyl group and the others axially orientated. The C—Br bond lengthsvary from 1.942 (4) to1.964 (4) Å. In the crystal, weak C—H...Ocarbonyl hydrogen-bonding interactions generate chains extending along the b-axis direction. Also present in the structure are two short intermolecular Br...Omethoxy interactions [3.020 (3) and 3.073 (4) Å].
