Abstract

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.
