✦ Synopsis
The 1,1Ј-bis(chlorostannyl)-substituted ferrocenes Fe(C 5 H 4 -investigated by temperature-dependent 119 Sn-and 57 Fe-Mössbauer spectroscopy. The electrochemistry of 1-5 gave SnMe 2 Cl) 2 (2), Fe(C 5 H 4 -SnMeCl 2 ) 2 (3) and Fe(C 5 H 4 -SnCl 3 ) 2 (4) were prepared, starting from 1,1Ј-bis(trimethyl-evidence of reversible one-electron oxidation processes. The molecular structure of 1,1Ј-bis(trichlorostannyl)ferrocene (4) stannyl)ferrocene (1). Treatment of the chlorides with Li[AlH 4 ] afforded the 1,1Ј-bis(hydridostannyl)-subsituted was determined by X-ray structural analysis, and there was no indication of intra-or intermolecular Sn 6) and Fe(C 5 H 4 -SnH 3 ) 2 (7), respectively.
