Twinning by merohedry in cyclohexanone oxime: A revised structure

Abstract:

The crystal structure of cyclohexanone oxime, C6H 11NO, was reported as severely disordered in the trigonal non-centro-symmetric space group P3 [Olivato, Ribeiro, Zukerman-Schpector & Bombieri (2001). Acta Cryst. B57, 705-713]. Reinvestigation of the crystal structure as twinned by merohedry in the trigonal centrosymmetric space group P3̄, with a twofold rotation about [001] as twin law, resulted in a well ordered structure and low R values. The asymmetric unit contains three independent molecules, existing as a hydrogen-bonded trimer, having an R 33(9) graph set.
