The crystal packing exhibits weak inter-molecular Cl⋯Cl contacts of 3.279 (4) Å, π-π inter-actions between the substituted Cp rings of two neighbouring 2-chloro-1-ferrocenyl-ethanone mol-ecules [centroid-centroid distance = 3.534 (3) Å], and weak inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds.Acta crystallographica.
