Abstract: The ¹³C, ¹¹⁹Sn NMR spectra of several organotinferrocence derivatives recently prepared were recorded and ¹³CNMR spectal peaks assigned, so the structures of this kind of compounds are confirmed further. The influence of variation of X incompounds with structure ofon chemical shift of ¹¹⁹Sn is discussed em-phatically It is found that change of X has little effect on ¹¹⁹Sn N-Sn transdirect coordination in the compoundwas also investigated.
