چکیده
The title cocrystal, 0.796C(19)H(16)N(4)·0.204C(18)H(14)N(4), 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). Inter-molecular π-π inter-actions with a centroid-to-centroid distance of 3.7371 (8) Å are observed in the crystal packing.

The mol-ecule of the title Schiff base compound, C(19)H(16)N(4), has crystallographic twofold rotation symmetry. The imino group is coplanar with the aromatic ring. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the central methyl-ene bridge. The packing of the mol-ecules is controlled by C-H⋯π inter-actions.

The mol-ecule of the title compound, C(20)H(20)Br(2)N(2)O(2), lies on a twofold axis. It contains two stereogenic C atoms with R chirality and thus it is the enatiomerically pure R,R-diastereomer. There is an intra-molecular O-H⋯N hydrogen bond.
