Abstract
(2-Acetylferrocen-1-yl)boronic acid, [Fe(C5H5)(C7H8BO3)] or 2-C(O)CH3-1-B(OH)2–Fc [Fc = Fe(η5-C5H3)(η5-C5H5)], crystallizes in the centrosymmetric space group P21/n. The boronic acid functionality interacts via intramolecular hydrogen bonds with the acetyl group and with the –B(OH)2 functionality of an adjacent molecule. The resulting centrosymmetric dimer exhibits an anti-positioning of the ferrocenyl moieties towards the central B2O4 plane. Consequently, an (Rp
,Sp
)-, i.e. a meso configuration is present for this dimer. In the crystal, weak C—H...O hydrogen bonds consolidate the molecular packing.
