(±)-Cyclo-hexane-1,2-diyl bis-(4-nitro-benzoate).

ABSTRACT: The crystal structure of the title compound, C(20)H(18)N(2)O(8), has been investigated to establish the relative stereochemistry between the ester groups. The cyclo-hexane ring adopts a chair conformation, in which the two ester groups occupy the adjacent equatorial positions in a trans relationship with each other. The mol-ecules assemble in the crystal as chains along the c axis via C-H⋯π inter-actions between the cyclo-hexane ring and a pair of nitro-phenyl rings of the neighbouring mol-ecule. Also observed are π-π stacking inter-actions between the nitro-phenyl rings of neighbouring chains, with a perpendicular distance between these rings of 3.409 Å and a slippage of 0.969 Å.
