Acetylferrocene–2-chloro-1-ferrocenylethanone (1/1)

Abstract

In the title co-crystal, [Fe(C5H5)(C7H6ClO)][Fe(C5H5)(C7H7O)], both substituted ferrocene molecules show the expected sandwich structure. The crystal packing exhibits weak intermolecular Cl...Cl contacts of 3.279 (4) Å, π–π interactions between the substituted Cp rings of two neighbouring 2-chloro-1-ferrocenylethanone molecules [centroid–centroid distance = 3.534 (3) Å], and weak intermolecular C—H...O and C—H...Cl hydrogen bonds.
