6,6'-Dimeth­oxy-2,2'-{[(E,E)-hydrazine-1,2-diyl­idene]bis­(methanylyl­idene)}diphenol methanol disolvate

The title compound, C₁₆H₁₆N₂O₄·2CH₃OH, is a hydrazone in an E geometric arrangement, with an inversion centre at the mid-point of the N-N bond. A symmetry-related pair of six-membered hydrogen-bonded rings [graph-set motif S¹₁(6)] are present for the terminal vanillin-imine moieties. Two lattice methanol solvent mol­ecules are present per formula unit (Z' = 1/2), which form hydrogen-bonded chains along [010] with two orientations due to disorder of the methanol H-atom.
