Crystal structure of 2-(4-chloro-phen-yl)-2-oxoethyl 3-bromo-benzoate.

ABSTRACT: 2-(4-Chloro-phen-yl)-2-oxoethyl 3-bromo-benzoate, C15H10BrClO3, was synthesized in a single-step reaction by condensation of 3-bromo-benzoic acid with 2-bromo-1-(4-chloro-phen-yl)ethanone in di-methyl-formamide in the presence of tri-ethyl-amine as a catalyst. The structure consists of an aryl ketone moiety linked to an aryl ester unit by a methyl-ene 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, mol-ecules form five separate sets of inversion dimers. Three of these are generated by two C-H⋯O inter-actions and a C-H⋯Br contact, and form chains along c and along the ab cell diagonal. In addition, two inversion-related
