2,4-Dibromo-6-[(E)-({3-[(E)-(3,5-dibromo-2-oxidobenzyl­idene)aza­nium­yl]-2,2-dimethyl­prop­yl}iminium­yl)meth­yl]phenolate

In the title mol­ecule, C₁₉H₁₈Br₄N₂O₂, the dihedral angle between the benzene rings is 73.9 (2)°. Two intra­molecular N—H...O hydrogen bonds make S(6) ring motifs. In the crystal, mol­ecules are linked via C—H...O inter­actions, forming chains propagating along the a-axis directon. A short C...Br [3.401 (5) Å] contact is present in the crystal structure, which is further stabilized by a π–π inter­action [centroid–centroid distance = 3.739 (3) Å].

{4,4′,6,6′-Tetra­bromo-2,2′-[(2,2-dimethyl­propane-1,3-di­yl)bis­(nitrilo­methanylyl­idene)]diphenolato}copper(II)

In the title compound, [Cu(C₁₉H₁₆Br₄N₂O₂)], the Cu^II ion and the substituted C atom of the diamine fragment lie on a crystallographic twofold rotation axis. The geometry around the Cu^II ion is distorted square-planar, which is defined by the N₂O₂ donor atoms of the coordinated Schiff base ligand. The dihedral angle between the symmetry-related substituted benzene rings is 25.33 (14)°. The crystal structure is stabilized by an inter­molecular π–π inter­action [centroid–centroid distance = 3.8891 (18) Å].
