Solution Studies by NMR

The first extensive NMR studies of deltahedral Zintl ions were carried out by Rudolph and coworkers. Using Sn, Sn, and Pb NMR they were the first to show that the homo- and hetero-atomic nine-atom deltahedral clusters Sng, Pbg, Sng- Ge , and Sn9 j Pbj are fluxional in solution. The homo-atomic clusters exhibit single resonances while multiple signals were observed for the hetero-atomic species due to their different stoichiometries, with one signal per stoichiometry. In addition to this, all the clusters show single spin-spin couplings of the types Sn— Sn, Sn- ° Pb, and Sn— Pb. These observations indicate that, on the NMR timescale, all atoms of the cluster are equivalent by dynamic and
