1,5-Bis(2-hy­droxy-3-meth­oxy­benzyl­idene)carbonohydrazide methanol 0.47-solvate

In the title compound, C₁₇H₁₈N₄O₅·0.47CH₃OH, the virtually planar (r.m.s. deviation = 0.128 Å) carbonohydrazide mol­ecule is located on a twofold axis and conformation of its C=N bonds is E. There are short intra­molecular O—H...N hydrogen bonds between the hy­droxy groups and hydrazide N atoms. In the crystal, bifurcated N—H...(O,O) hydrogen bonds assemble the carbonohydrazide mol­ecules into a three-dimensional network. There are C₂ symmetric voids in this network, 47% of which are occupied by disordered methanol mol­ecules.
