Abstract
In the title compound, C11H7Br3ClN, the quinoline ring system is approximately planar (r.m.s. = 0.011 Å). In the crystal, mol-ecules are linked by C-H⋯Br inter-actions forming chains along [10-1]. The chains are linked by C-H⋯π and π-π inter-actions involving inversion-related pyridine rings [inter-centroid distance = 3.608 (4) Å], forming sheets parallel to (10-1). Within the sheets, there are two significant short inter-actions involving a Br⋯Cl contact of 3.4904 (18) Å and a Br⋯N contact of 3.187 (6) Å, both of which are significantly shorter than the sum of their van der Waals radii.Entities:

| Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
