The title compound 1,3-bis(p-nitrophenoxy)propane was synthesized by nucleophilic substitution of p-nitrophenol and 1,3-dibromopropane. Single crystal X-ray diffraction analysis reveals that the molecule in the solid state packs in the monoclinic P2/n space group with crystal cell parameters a = 17.465(5) Å, b = 4.8433(13) Å, c = 17.610(5) Å, β = 100.290(6)º, V = 1465.6(7) Å3, Dcalc = 1.442 g/cm−3. Two half-molecules are located in the asymmetric unit which are each completed by twofold symmetry making Z = 4, Z′ = 1. The title compound 1, 3-bis (p-nitrophenoxy) propane was prepared from p-nitrophenol and 1, 3-dibromopropane, crystallized from an ethanolic solution, and the structure was obtained by single crystal X-ray diffraction: monoclinic, P2/n, a = 17.465(5) Å, b = 4.8433(13) Å, c = 17.610(5) Å, β = 100.290(6)°, V = 1465.6(7) Å3.
