title: Substituent-dependent exchange mechanisms in highly fluxional RSn9(3-) anions.
abstract: 119Sn NMR studies show that the RSn9(3-) ions (R=i-Pr, Sn(C6H11)3) are highly fluxional in solution, where the exchange mechanisms involve rapid migration of the R group in the latter but not in the former.
