Abstract
In the title compound {systematic name: 4,4′-[1,1′-(hydrazinediylidene)bis(ethan-1-yl-1-ylidene)]bis(benzene-1,3-diol)}, C16H16N2O4·2C3H7NO, the (E,E)-2′,4′-dihydroxyacetophenone azine molecule is centrosymmetric, the mid-point of the N—N bond being located on an inversion centre. All the non-H atoms of the azine molecule are approximately coplanar, the maximum deviation being 0.017 (2) Å. An intramolecular O—H...N hydrogen bond occurs between the azine N atom and the hydroxy group. In the crystal, azine and dimethylformamide solvent molecules are linked by O—H...O hydrogen bonds.
