Crystal structure of 2-(4-chloro­phen­yl)-2-oxoethyl 3-bromo­benzoate

2-(4-Chloro­phen­yl)-2-oxoethyl 3-bromo­benzoate, C(15)H(10)BrClO(3), was synthesized in a single-step reaction by condensation of 3-bromo­benzoic acid with 2-bromo-1-(4-chloro­phen­yl)ethanone in di­methyl­formamide in the presence of tri­ethyl­amine as a catalyst. The structure consists of an aryl ketone moiety linked to an aryl ester unit by a methyl­ene group. Both units are reasonably planar (r.m.s. deviations of 0.119 and 0.010 Å for the aryl ketone and aryl ester units, respectively) and are almost orthogonal, with an angle of 88.60 (3)° between them. In the crystal, mol­ecules form five separate sets of inversion dimers. Three of these are generated by two C—H⋯O inter­actions and a C—H⋯Br contact, and form chains along c and along the ab cell diagonal. In addition, two inversion-related π–π stacking inter­actions between like aryl rings again form chains of mol­ecules but in this instance along the bc diagonal. These contacts generate infinite layers of mol­ecules parallel to (011) and stack the mol­ecules along the a-axis direction.
