Popis: In the crystal structure of (2-acetyl­ferrocen-1-yl)boronic acid, centrosymmetric dimers held together by –B(OH)⋯O hydrogen bonds are present.
(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.
