cis- and trans-4-tert-Butylcyclohexyl p-Nitrobenzenesulfonate at 130K

The structures of the title axial and equatorial cyclohexyl p-nitrobenzenesulfonate esters, C₁₆H₂₃NO₅S, determined at 130 K are reported. The C_alkyl-O_ester bond distances of 1.487 (2) and 1.492 (2) Å are not significantly different from one another. The geometry of the sulfonate function with respect to both the phenyl and cyclohexane rings is essentially identical in both structures.
