The title compound, C15H24N2O2, crystallizes with two unique molecules, (I) and (II), in the asymmetric unit, differing in the orientation of the acryloyl units with respect to the piperidine rings. The acrylamide units are essentially planar in both molecules (r.m.s. deviations = 0.042 and 0.024 angstrom, respectively), as are the C3N chains of the acryloyl units. The carbonyl O atoms of the acryloyl systems lie significantly out of these planes, viz. by -0.171 (9) angstrom for molecule (I) and by 0.33 (1) angstrom for molecule (II). The acrylamide and acryloyl planes are inclined at 68.7 (4)degrees and 59.8 (3)degrees in the two molecules. The piperidine rings each adopt twist boat conformations. In the crystal, strong N-H center dot center dot center dot O hydrogen bonds link the molecules into zigzag C(4) chains along b. Additional C-H center dot center dot center dot O contacts result in the formation of stacks along a.
