Abstract

In the thiomolybdates Mo04_wSn 2~ (rc = 0, 1, 2, 3, 4 ) , four different nuclei can give rise to NMR signals: 1 7 0 , 33S, 9 5Mo and 9 7Mo. All of those are quadrupolar nuclei with relatively low NMR receptivity. The study of different nuclei in one single compound yields more information with respect to structure and ligand exchange. Second, experiments of this type can show the advantages and limits of the NMR signals of a certain nucleus in the compound investigated. Most recently 9 5Mo NMR was used to study simple and low molecular weight compounds [1 — 4 ] , and it was possible to identify different molybdenum (VI) chalcogenide anions in aqueous solutions [ 5 ] . The rather narrow linewidth of the 9 5Mo NMR signal in MoS42~ allowed measurements of the small 32S-34S isotope effect [ 6 ] . Because the quadrupole moment of 9 7Mo is much larger than that of
