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

The racemic title compound, [Fe(C5H5)(C16H27O2)], comprises an alpha,omega-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)degrees. The ferrocene rings are almost eclipsed and parallel. The crystal structure features O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds and C-H center dot center dot center dot pi contacts that stack the molecules along the c-axis direction. A Hirshfeld surface analysis reveals that H center dot center dot center dot H interactions (83.2%) dominate the surface contacts.
