The crystal structure of 2-(2′,5′-dinitrophenoxy)-tetrahydropyran¹

The crystal structure of the title compound (1) has been determined [space group P21/n, a = 7.940(2), b = 7.911(2), c = 19.455(4) Å, β = 98.34(2)°, Z = 4] and refined to R0.050 for 1542 unique observed reflections. The exocyclic acetal bond length is within half an e.s.d. of that predicted by a previously published bond length/reactivity correlation (Jones and Kirby, 1979).
