The compounds were identified by 1H, 119Sn, 15N, 31P, and 183W NMR, ESI-MS, and elemental analyses. The key connectivity of the Sn−Cl center with the amine was clarified by the observation of 3J Sn−H couplings (Sn from the polyoxometalate cluster and H from the amine moiety) in a 2D 119Sn−1H heteronuclear multiple-bond correlation NMR experiment. This new, rather simple synthetic method was also utilized for preparing amino acid−polyoxometalate hybrid compounds. %I ACS Publications
