Abstract
The structure of 2-(4′-carbomethoxy-2′-nitrophenoxy)-1,3,5-trimethylbenzene, C17H17NO5, has been determined by X-ray diffraction. The crystals are monoclinic, a = 8.352(4), b = 17.892(10), c = 10.966(6) Å, β = 100.59(3) °, P21/c with Z = 4. The intensities of 3877 independent reflections were measured on a four circle diffractometer; 2272 of these reflections were used to obtain a final least-squares residual of 0.053 and traditional R factor of 0.054. The general conformation is similar to that found earlier for differently substituted diphenyl ethers. Comparison of this structure with those previously determined indicates that distortions in ring angles are primarily a result of electronic rather than steric effects.
