(±)-Cyclohexane-1,2-diyl bis(4-nitrobenzoate)

The crystal structure of the title compound, C20H18N2O8, has been investigated to establish the relative stereochemistry between the ester groups. The cyclohexane ring adopts a chair conformation, in which the two ester groups occupy the adjacent equatorial positions in a trans relationship with each other. The molecules assemble in the crystal as chains along the c axis via C—H...π interactions between the cyclohexane ring and a pair of nitrophenyl rings of the neighbouring molecule. Also observed are π–π stacking interactions between the nitrophenyl rings of neighbouring chains, with a perpendicular distance between these rings of 3.409 Å and a slippage of 0.969 Å.
