ABSTRACT: The asymmetric units of the compounds, C₈H₅BrCl₂O (I), and C₉H₈Br₂O (II), contain two and one crystallographically independent mol-ecules, respectively. In compound (I), the planar rings are oriented at a dihedral angle of 13.23 (8)°. In crystals of both compounds, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into infinite chains along the b-axis direction. In crystal of (I), there are π-π inter-actions between the centroids of the parallel rings with centroid-to-centroid distances of 3.5974 (14), 3.6178 (16) and 3.9387 (16) Å while neither π-π nor C-H⋯ π(ring) inter-actions are present in (II). The Hirshfeld surface analyses of the crystal structures indicate that the most important contributions for the
