Abstract
The structure of the hemihydrochloride of the defensive N-oxide alkaloid of the ladybird, coccinellin, C13H23NO, has been determined by single-crystal X-ray diffraction; two molecules are linked together through their oxygen atom via a symmetrical hydrogen bond, the O–O distance being 2·43 Å.Keywords
