Cover illustration: The asymmetric unit of C27H36O3, a chalcone derivative with antimicrobial activity, consists of two bow-shaped molecules, with the long alkoxyl chains adopting all-trans conformations. Intramolecular O-HO hydrogen bonds and weak intermolecular C-H interactions are seen in the crystal structure. See Razak et al. [Acta Cryst. (2009). E65, o1133-o1134].
