title: 1-(2,2-Di-chloro-acet-yl)-3-ethyl-2,6-di-phenyl-piperidin-4-one.
abstract: The asymmetric unit of the title compound, C21H21Cl2NO2, contains two independent mol-ecules that show similar geometrical features. The piperidine ring adopts a distorted boat conformation. The phenyl rings substituted at the 2- and 6-positions of the piperidine ring are oriented at angles of 65.4 (1) [64.7 (2)°] and 89.2 (1)° [86.3 (2)°] with respect to the least-squares plane of the piperidine ring. In the crystal, adjacent mol-ecules are linked by a network of C-H⋯O inter-actions, forming a C(6) chain along the c-axis direction.
