Abstract
The crystal structure of 1,3-diphenyl-propan-2-one oxime, C15H15NO, is described. The compound crystallises in the monoclinic space group C2/c. Centrosymmetrically related molecules are linked to form R22 (6) dimers. An update, since 2003, of a systematic analysis of the hydrogen bonding patterns in oxime structures with and without competitive O-H...A type acceptors (an acceptor other than the nitrogen of the oxime) functional group is made, taking into account their moieties. The majority of these oximes form dimeric, R22 (6), structures but R33 (8) and R44 (12) were also found. C3 chains which were classically claimed as the usual oxime H-bond pattern were rarely observed. They are mostly found in aldoxime structures.Keywords
