Organotin-Oxido Cluster-Based Multiferrocenyl Complexes Obtained by Hydrolysis of Ferrocenyl-Functionalized Organotin Chlorides

摘要

Three organotin-oxido clusters were formed by hydrolysis of ferrocenyl-functionalized organotin chloride precursors in the presence of NaEPh (E=S, Se). [R~(Fc)SnCl_3·HCl] (C; R~(Fc) = CMe_2CH_2C(Me)=N-N=C(Me)Fc) and [SnCl_6]~(2-) formed {(R~(Fc)SnCl_2)_3[Sn(OH)_6]}[SnCl_3] (3a) and {(R~(Fc)SnCl_2)_3[Sn(OH)_6]}[PhSeO_3] (3b), bearing an unprecedented [Sn_4O_6] unit, in a one-pot synthesis or stepwise through [(R~(Fc)SnCl_2)_2Se] (1) plus [(R~(Fc)SnCl_2)SePh] (2). A onepot reaction starting out from FcSnCl_3 gave [(FcSn)_9(OH)_6O_8Cl_5] (4), which represents the largest Fcdecorated Sn/O cluster reported to date.
