Crystal structure of 2-(3,5-dimethoxyphenylamino)-3-chloronaphthalene-1,4-dione

Abstract

2-(3,5-Dimethoxyphenylamino)-3-chloronaphthalene-1,4-dione compound was prepared from the nucleophilic substitution reaction of 2,3-dichloro-1,4-naphthoquinone with 3,5-dimethoxyphenylamine at reflux temperature according to literature reported previously. Single-crystal X-ray diffraction analysis was carried out to confirm the structure of the title compound. The title compound, C₁₈H₁₄ClNO₄, crystallizes in the triclinic space group P-1, a = 7.0016(6) Å, b = 7.7937(6) Å, c = 15.6218(11) Å, β = 97.238(4)°, V = 782.44(11) ų, Z = 2, R₁ = 0.0525, wR₂ = 0.1329.
