The crystal structure of the title compound, C13H 16N2O4, (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 β to N. The C-OPNB (PNB is p-nitrobenzoate) bond distance is 1.4630 (16) Å, which is not significantly different from the corresponding C-OPNB distance in 4-tert-butyl-cyclohexyl 4-nitrobenzoate. The structure of (1) was determined at 130 K. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved.
