Abstract The crystal structure of 2,4-dinitronaphthyl-2′,6′-dimethylphenyl ether, C18H14N2O5, has been determined by three-dimensional x-ray methods, as part of a study of hindered aryl ethers. The crystals are monoclinic, space groupP21/c witha = 13.416(1),b = 8.479(1),c = 14.808(2) Å, β = 111.65(1) ° andZ = 4. The structure was solved by direct methods using program REL and was refined by full-matrix least squares to anR value of 0.050. The torsion angles that describe the diphenyl ether conformation are 60/22 ° for C2′-C1′-O1-C1/C1′-O1-C1-C2, respectively. The average torsion angles for other naphthalene phenyl ethers are 65/25 °. There are no hydrogen bonds in this structure.
