2-{[2-(2-Hy-droxy-3-meth-oxy-benzyl-idene)hydrazin-1-yl-idene]meth-yl}-6-meth-oxy-phenol.

Project description: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.
