2-{[4-(Phenyldiazenyl)phenyl]iminomethyl}phenol
The mol-ecule of the title compound, C(19)H(15)N(3)O, is approximately planar and displays a trans configuration with respect to the C=N and N=N double bonds. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. The dihedral angles between the hydroxy-phenyl ring and the phenyl and benzene rings are 4.31 (8) and 6.60 (8)°, respectively. The dihedral angle between the phenyl and ...
