Popis:	Lithiation of 2-pyridylferrocene with n-butyllithium followed by addition of paraformaldehyde, dimethylformamide, or solid CO2 gives the 1, 2-disubstituted ferrocenes [{C5H3R(2-C5H4N)}FeCp] [R = CH2OH (2), CHO (3), COOH (4)]. Treatment of these compounds with [PtCl2(DMSO)2] gives the cycloplatinated complexes σ-Pt[{C5H2R(2-C5H4N)}FeCp]Cl(DMSO) with R = CH2OH (5), CHO (6) and H, the latter one as the only isolable product of decomposition. The crystal and molecular structures of 3–5 were determined and show the importance of hydrogen-bonds in these compounds, which leads to polymeric structures.
