1-Ferrocenyl-3-(4-n-octoxylphen-yl)propane-1,3-dione

The title compound, [Fe(C5H5)(C22H27O3)], which forms an extended conjugated system and appears in the enol form, is mainly stabilized by an intra-molecular hydrogen bond. The Fe - C bond distances are nearly equal with a mean value of 2.0312 Å. The two cyclo-penta-dienyl rings are almost parallel to each other, as shown by the dihedral angle of 0.97 (17)°. In the structure, ferrocenyl is the more powerful electron-donating group, with the result that the carbonyl group substituted on the benzene ring has the enol form. © International Union of Crystallography 2007.
