2-Chloro-3-(4-chlorobenzamido)-1,4-naphthoquinone

Y. Brandy, R. J. Butcher, T. A. Adesiyun, S. Berhe and O. Bakare

Abstract: The naphthoquinone ring is almost perpendicular [dihedral angle 71.02 (3)°] to the phenyl group of the title compound, C₁₇H₉Cl₂NO₃, while the dihedral angle between the amide group and the 4-chlorophenyl ring is 21.9 (2)°. The conformation of the N-H and C=O bonds are anti to each other. N-HCl hydrogen bonds link the molecules into chains in the a-axis direction. In addition, these chains are linked by weak intermolecular C-HO interactions.
