Synthesis, crystal structure and Hirshfeld surface analysis of 1-ferrocenylundecane-1,11-diol

Abstract

The racemic title compound, [Fe(C5H5)(C16H27O2)], comprises an α,ω-diol-substituted undecyl chain with a ferrocenyl substituent at at one terminus. The alkane chain is inclined to the substituted ring of the ferrocene grouping by 84.22 (13)°. The ferrocene rings are almost eclipsed and parallel. The crystal structure features O—H...O and C—H...O hydrogen bonds and C—H...π contacts that stack the molecules along the c-axis direction. A Hirshfeld surface analysis reveals that H...H interactions (83.2%) dominate the surface contacts.
