4-(2-Methoxy-4-nitrophenyldiazenyl)phenol monohydrate

X.-L. You, Y. Zhang and D.-C. Zhang

Abstract: The organic molecule of the title compound, C₁₃H₁₁N₃O₄·H₂O, is essentially planar. The two benzene rings make a dihedral angle of only 1.6 (1)° and the nitro group is rotated only 3.6 (1)° from the plane of its attached benzene ring. In the crystal structure, the planar molecules stack along [100] through - interactions, and these stacks interact laterally through strong and weak hydrogen bonds. The solvent water molecule is involved in all of the strong interactions through O-HO(water), NH-O(water) and OH-O(water) hydrogen bonds.
