ABSTRACT
The title compound, C(15)H(24)N(2)O(2), crystallizes with two unique mol-ecules, (I) and (II), in the asymmetric unit, differing in the orientation of the acryloyl units with respect to the piperidine rings. The acryl-amide units are essentially planar in both mol-ecules (r.m.s. deviations = 0.042 and 0.024â
Å, respectively), as are the C(3)N chains of the acryloyl units. The carbonyl O atoms of the acryloyl systems lie significantly out of these planes, viz. by -0.171â
(9)â
Å for molecule (I) and by 0.33â
(1)â
Å for molecule (II). The acryl-amide and acryloyl planes are inclined at 68.7â
(4)° and 59.8â
(3)° in the two mol-ecules. The piperidine rings each adopt twist boat conformations. In the crystal, strong N-Hâ¯O hydrogen bonds link the mol-ecules into zigzag C(4) chains along b. Additional C-Hâ¯O contacts result in the formation of stacks along a.
