Abstract

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. Abstract : Decorated clusters : Two new Sn/O cluster‐based multiferrocenyl complexes were formed by hydrolysis of ferrocenyl‐substituted organotin trichlorides. The structure of one of them, which can be synthesized either via a mononuclear and a dinuclear intermediate complex or in a one‐pot reaction, is based on a [Sn4 O6 ] unit. The second one is obtained from a corresponding reaction of FcSnCl3 and contains nine Fc units on the cluster surface (see figure).
