In the title compound, C8H6BrCl3O, there is a weak intra­molecular C—H⋯Cl hydrogen bond involving the O bound methylene group. Intermolecular Cl⋯Cl contacts [3.482 (2) Å] are present in the crystal structure.

Key indicators: single-crystal X-ray study; T = 294 K; mean (C-C) = 0.005 Å; R factor = 0.059; wR factor = 0.155; data-to-parameter ratio = 14.5.In the molecule of the title compound, C 13 H 12 O, the two aromatic rings are oriented at a dihedral angle of 2.90 (3). An intramolecular C-HÁ Á ÁO hydrogen bond results in the formation of a non-planar six-membered ring, which adopts an envelope conformation. In the crystal structure, intermolecular C-HÁ Á ÁO hydrogen bonds link the molecules. Related literature ExperimentalCrystal data

In the mol­ecule of the title compound, C8H8BrClO, the Cl atom lies slightly out of the aromatic ring plane [displacement = 0.072 (3) Å]. In the crystal structure, a π–π contact between the phenyl rings [centroid–centroid distance = 3.699 (3) Å] may stabilize the structure. There also exists a C—H⋯π contact between the methyl­ene group and the chloro­phenyl ring.

In the crystal structure of the title compound, C9H11BrO2, mol­ecules are stacked parallel to the b-axis direction, forming double layers in which the molecules are arranged head-to-head, with the bromo­methyl groups pointing towards each other.
