Abstract
Polysubstituted piperidones, viz. the title compounds, C27H25NO, (I), C27H23Cl2NO, (II), and C27H23Cl2NO, (III), adopt sofa conformations. The molecular packing in (I) and (II) is a result of van der Waals interactions, whereas in (III), a C-H center dot center dot center dot O interaction is also found.
