The crystal structure of cyclohexanone oxime, C(6)H(11)NO, was reported as severely disordered in the trigonal non-centrosymmetric space group P3 [Olivato, Ribeiro, Zukerman-Schpector & Bombieri (2001). Acta Cryst. B57, 705-713]. Re-investigation of the crystal structure as twinned by merohedry in the trigonal centrosymmetric space group P-3, 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(3)(3)(9) graph set.
环己酮肟（C₆H₁₁NO）的晶体结构据报道在三方非中心对称空间群P3中严重无序[奥利瓦托、里贝罗、祖克曼 - 施佩克特和邦比耶里（2001年）。《晶体学报》B57，705 - 713页]。对该晶体结构进行重新研究，发现其在三方中心对称空间群P - 3中以体心孪晶形式存在，孪晶法则为绕[001]轴的二次旋转，得到了一个有序的结构和较低的R值。不对称单元包含三个独立分子，以氢键连接的三聚体形式存在，具有R₃³(9)图集合。
