Abstract

Three organotin-oxido clusters were formed by hydrolysis of ferrocenyl-functionalized organotin chloride precursors in the presence of NaEPh (E=S, Se). [R(Fc) SnCl3 ⋅HCl] (C; R(Fc) = CMe2 CH2 C(Me)=N-N=C(Me)Fc) and [SnCl6 ](2-) formed {(R(Fc) SnCl2 )3 [Sn(OH)6 ]}[SnCl3 ] (3 a) and {(R(Fc) SnCl2 )3 [Sn(OH)6 ]}[PhSeO3 ] (3 b), bearing an unprecedented [Sn4 O6 ] unit, in a one-pot synthesis or stepwise through [(R(Fc) SnCl2 )2 Se] (1) plus [(R(Fc) SnCl2 )SePh] (2). A one-pot reaction starting out from FcSnCl3 gave [(FcSn)9 (OH)6 O8 Cl5 ] (4), which represents the largest Fc-decorated Sn/O cluster reported to date.
