4,4'-[Propane-1,2-diylbis(nitrilomethylidyne)]dibenzonitrile-4,4'-[ethane-1,2-diylbis(nitrilomethylidyne)]dibenzonitrile [0.796 (2)/0.204 (2)]

Abstract: The title cocrystal, 0.796C₁₉H₁₆N₄·0.204C₁₈H₁₄N₄, is a disordered mixture of two potentially bidentate Schiff base ligands. The difference in the two components of the cocrystal is the replacement of the methyl group in the linkage between the imine N atoms in the major component of the Schiff base ligand by an H atom. The imino (C=N) functional groups are coplanar with the benzene rings (only the major component) and extend in opposite directions (both components). Intermolecular - interactions with a centroid-to-centroid distance of 3.7371 (8) Å are observed in the crystal packing.
