N-Methyl-4-piperidyl p-nitrobenzoate at 130 K

L. Andrau and J. White

Abstract: The crystal structure of the title compound, C₁₃H₁₆N₂O₄, (1), reveals that the molecule exists in the solid state in the equatorial conformation. Thus, the through-bond interaction present in the axial conformation is not strong enough to overcome the syn-diaxial interactions between the axial methyl substituent and the axial H atoms on each of the ring C atoms to N. The C-O_PNB (PNB is p-nitrobenzoate) bond distance is 1.4630 (16) Å, which is not significantly different from the corresponding C-O_PNB distance in 4-tert-butylcyclohexyl 4-nitrobenzoate. The structure of (1) was determined at 130 K.
