title: 1-Formyl-r-2,c-6-bis-(4-methoxy-phen-yl)-t-3,t-5-dimethyl-piperidin-4-one.
abstract: In the title compound, C(22)H(25)NO(4), the piperidine ring adopts a distorted boat conformation. The methyl groups at the 3 and 5 positions of the piperidine ring are in axial and equatorial orientations, respectively. Both H and O atoms in the aldehyde group are disordered over two positions with occupancies of 0.534 (5) and 0.466 (5). In the crystal, the mol-ecules are linked into a three-dimensional network by C-H⋯O hydrogen bonds.
