(2-Bromo­acet­yl)ferrocene

In the title mol­ecule, [Fe(C(5)H(5))(C(7)H(6)BrO)], 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.
