title: 2-{[2-(2-Hy-droxy-3-meth-oxy-benzyl-idene)hydrazin-1-yl-idene]meth-yl}-6-meth-oxy-phenol.
abstract: The title compound, C(16)H(16)N(2)O(4), was obtained from the reaction of hydrazine hydrate and o-vanilin in absolute ethanol. The mol-ecule is almost planar (except for the methyl H atoms), with a mean deviation from the plane of 0.0259 Å. The mol-ecular structure also exhibits an approximate non-crystallographic twofold axis. Intra-molecular O-H⋯N hydrogen bonds occur. In the crystal, inter-molecular C-H⋯O hydrogen bonds generate mol-ecular zigzag sheets. The sheets stack through C-H⋯π inter-actions, leading to a three-dimensional-network.
