Crystal structure of (2-acetyl-ferrocen-1-yl)boronic acid.

ABSTRACT: (2-Acetyl-ferrocen-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 inter-acts via intra-molecular hydrogen bonds with the acetyl group and with the -B(OH)₂ functionality of an adjacent mol-ecule. The resulting centrosymmetric dimer exhibits an anti-positioning of the ferrocenyl moieties towards the central B₂O₄ plane. Consequently, an (R_p ,S_p )-, i.e. a meso configuration is present for this dimer. In
