title: 4-[(E)-1-Naphthyl-diazen-yl]phenol.
abstract: The title compound (C. I. Solvent Yellow 8), C(16)H(12)N(2)O, crystallizes with two crystallographically independent mol-ecules in the asymmetric unit. The planarity of both mol-ecules is slightly distorted, the dihedral angles between the benzene ring and the naphthalene system being 9.04 (8) and 5.69 (3)°. In the crystal, O-H⋯N hydrogen bonds between the hydr-oxy groups and azo N atoms link the two symmetry-independent mol-ecules into a polymeric chain propagating in [001].
