| Summary: | The title compound [(N,N-dimethylamino)methyl]ferrocene, [Fe(C5H5)(C8H12N)], (1), is an interesting starting material for the synthesis of planar chiral 1,2-disubstituted ferrocenes, as demonstrated by the preparation of (Rp,Rp)-bis{2-[(dimethylamino)methyl]ferrocenyl}dimethylsilane, [Fe2(C5H5)2(C18H18N2Si)], (2), from the lithiated derivative of 1. The configuration of the lithium compound is unchanged after the substitution reaction and the chirality is preserved in space group P212121. In both compounds, the Cp rings adopt eclipsed conformations. Hirshfeld surface analysis was used to investigate the intermolecular interactions, and showed that H...H (van der Waals) interactions dominate in both structures with contact percentages of 83.9 and 88.4% for 1 and 2, respectively.
