title: 2,2,6,6-Tetra-bromo-3,4,4,5-tetra-meth-oxy-cyclo-hexa-none.
abstract: In the title compound, C10H14Br4O5, synthesized from the meth-oxy Schiff base N-(pyridin-2-ylmeth-yl)meth-oxy-aniline and mol-ecular bromine, the cyclo-hexa-none ring has a chair conformation with one of the four meth-oxy 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⋯Ocarbon-yl hydrogen-bonding inter-actions generate chains extending along the b-axis direction. Also present in the structure are two short inter-molecular Br⋯Ometh-oxy inter-actions [3.020 (3) and 3.073 (4) Å].
