N,N'-Bis(4-bromo-benzyl-idene)butane-1,4-diamine.

ABSTRACT: The mol-ecule of the title Schiff base compound, C(18)H(18)Br(2)N(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the C=N bond. In the crystal structure, mol-ecules are linked into chains along [201] through inter-molecular Br?Br inter-actions [3.3747?(3)?Å], which are significantly shorter than the sum of the van der Waals radii for Br atoms (3.70?Å). The crystal structure is further stabilized by ?-? stacking inter-actions [centroid-centroid distance 3.6811?(11)?Å].

The mol-ecule of the title Schiff base compound, C(18)H(18)Br(2)N(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the C=N bond. In the crystal structure, mol-ecules are linked into chains along [201] through inter-molecular Br⋯Br inter-actions [3.3747 (3) Å], which are significantly shorter than the sum of the van der Waals radii for Br atoms (3.70 Å). The crystal structure is further stabilized by π-π stacking inter-actions [centroid-centroid di  ...[more]
