摘要：
Organophosphonyl and organosilyl derivatives of the trivacant tungstophosphate [(PW9O34)-W-V](9-) were investigated in solution by multinuclear (Si-29, P-31, W-183) magnetic resonance. In the absence of X-ray data, multinuclear NMR allows to predict the structural arrangement of the various hybrid organic-inorganic species under study. In particular W-183 NMR is especially useful to infer the overall symmetry of the polyoxotungstic framework.
