Notes:
The 1,1′-bis(chlorostannyl)-substituted ferrocenes Fe(C5H4-SnMe2Cl)2 (2), Fe(C5H4-SnMeCl2)2 (3) and Fe(C5H4-SnCl3)2 (4) were prepared, starting from 1,1′-bis(trimethylstannyl)ferrocene (1). Treatment of the chlorides with Li[AlH4] afforded the 1,1′-bis(hydridostannyl)-subsituted ferrocenes Fe(C5H4-SnMe2H)2 (5), Fe(C5H4-SnMeH2)2 (6) and Fe(C5H4-SnH3)2 (7), respectively. All complexes 1-7 were studied by 1H-, 13C-, and 119Sn-NMR spectroscopy with 1D and 2D techniques. The compounds 1-4 were investigated by temperature-dependent 119Sn- and 57Fe-Mössbauer spectroscopy. The electrochemistry of 1-5 gave evidence of reversible one-electron oxidation processes. The molecular structure of 1,1′-bis(trichlorostannyl)ferrocene (4) was determined by X-ray structural analysis, and there was no indication of intra- or intermolecular Sn···Cl···Sn interactions. This direct structural information proved to be consistent with both the Mössbauer and the solution NMR spectroscopic data.
