AbstractThe novel complex {[FcCH = CHCO2Sn(n-Bu)(2)](2)O}(2) (A) has been synthesized by the reaction of (n-Bu)(2)SnO with beta -FeCH = CHCO2H (Fc = ferrocenyl). This molecule has a center of the structure Sn-O-(Sn-2) -O-Sn by elemental analysis, IR and NMR (H-1, C-13 and Sn-119) spectra. A principle is put firstly forward to assign each carbon peak of the alkyl groups in the type of complex[(RCOOSnR ' (2))(2)O](2): (1) to distinguish the endo- and exo-cyclic tin using Sn-119 NMR spectrum. The Sn-119 signal with larger linewidth should be assigned as an endo-cyclic tin; (2) to find out which proton of the alkyl chain bonded with endo- (or exo-) cyclic tin using H-1-Sn-119 HMQC spectrum. The proton of cross peaks through (4)J(H-1-Sn-119) coupling which occurs simultaneously to both endo- and exo-cyclic tin should belong to one of the alkyl chain binding directly to endo-cyclic tin. The proton of cross peak through (4)J(H-1-Sn-119) coupling which occurs only to endo- cyclic tin should belong to one of the alkyl chain binding directly to exo-cyclic tin; (3) to assign each C-13 peak of the CH2 groups on alkyl chains through 2D C-13 - H-1 COSY spectrum; (4) to find out which C-13. peak of alkyl chains is bonded with endo- or exo-cyclic tin, according to general principle that the C-13: peak with higher field should correspond to the proton peak with higher field, that is, if the chemical shift of proton on the alkyl chain bonding directly to endo-cyclic tin locates at higher field, its related C-13 peak located at higher field should belong to endo-cyclic tin.
