The conformation of (1S,3S,4R)- 1,3,8-Tribromo-p-menthan-2-one

Abstract

The crystal structure of (1S,3S,4R)-1,3,8-tribromo-p-menthan-2-one has been determined from X-ray diffraction data and refined to a final residual of 0.075 for 635 'observed' reflections. Crystals are orthorhombic, of space group P2₁2₁2₁ with four molecules in a cell of dimensions a 15.248(3), b 12.189(3), c 7.201(2) Å. The analysis confirms that the molecule exists in a distorted twist-boat conformation.
