title: 2-[(E)-Phen-yl(2-phenyl-hydrazin-1-yl-idene)meth-yl]phenol.
abstract: In the title hydrazone derivative, C(19)H(16)N(2)O, a twist is found between the hy-droxy-phenyl and N-bound phenyl rings [dihedral angle = 24.37 (7)°]. The C-bound phenyl ring is almost perpendicular to each of these planes [dihedral angles = 75.30 (7) and 86.00 (7)°, respectively]. The conformation about the imine bond [1.2935 (17) Å] is E. The hy-droxy group forms an intra-molecular hydrogen bond with the imine N atom. Zigzag chains along [001] mediated by N-H⋯O hydrogen bonds feature in the crystal packing.
