Abstract
The crystal structure of zerumbone, C15H22O, extracted from
the rhizomes of Zingiber zerumbet
Smith, has been determined by single-crystal X-ray diffraction at 295(1) K and
refined by least squares to a residual of 0.051 for 925 'observed' reflections.
Crystals are monoclinic, space group P21/c, a 9.036(3), b 9.712(5), c 15.643(6) �, β 97.19(3)�, Z = 4.
Although the molecule has no chiral centre, the
presence of the three trans double
bonds confers considerable distortion and rigidity on the eleven-membered ring and renders the whole molecule chiral and potentially resolvable.
