title: 1,2-Bis(2-hy-droxy-5-methyl-benzyl-idene)hydrazine.
abstract: The mol-ecular structure of the title compound, C16H16N2O2, is stabilized by intra-molecular O-H⋯N hydrogen bonds with S(6) graph-set motifs, so that the mol-ecule is almost planar, with a C=N-N=C torsion angle of -179.7 (2)° and a dihedral angle of 1.82 (12)° between the aromatic rings. In the crystal, weak C-H⋯π inter-actions lead to the formation of a three-dimensional network.
