(2-Bromoacetyl)ferrocene

Abstract

In the title molecule, [Fe(C5H5)(C7H6BrO)], the C atoms of the substituted ring have disparate Fe—C bond lengths compared with the unsubstituted ring. In the bromoacetyl residue, the Br and O atoms are co-planar [the O—C—C—Br torsion angle is 5.7 (4)°] and are syn to each other. Helical supramolecular chains along the b axis are formed in the crystal structure mediated by C—H...O contacts; the carbonyl-O atom is bifurcated. The chains are linked into layers by C—H...π(unsubstituted ring) interactions that stack along the a-axis direction.
