Abstract:
In the title compound C11H9BrCl2O2, which represents the Z isomer, the methyl-acrylate moiety is essentially planar within 0.039 (2) Å and has an extended trans configuration. The benzene ring makes a dihedral angle of 28.3 (1)° with the mean plane of the methyl-acrylate moiety. The crystal packing is characterized by C-H⋯O hydrogen bonding and halogen-halogen inter-actions [Cl⋯Cl = 3.486 (3) Å], resulting in the formation of R 2 (2)(11) ring motifs and connecting the mol-ecules into chains propagating along the b axis.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
