✦ Synopsis
A procedure for structural characterization based on X-ray diffraction (XRD) and on a set of twodimensional solid-state NMR experiments is proposed. It has been applied to a new gallophosphate oxyfluorinated compound, T(T D amine)-GaPO [Ga 4 PO 4 3 HPO 4 F 3Ð T]. To complement and validate structural information obtained by XRD, a set of three solid-state NMR experiments-RFDR for fluorine-19, double quanta for phosphorus-31 and HETCOR between fluorine and phosphorus-facilitate the analysis of the topology of homoatomic and heteroatomic sub-networks of fluorine and phosphorus included in the inorganic framework of this material. The efficiency of this combination of NMR experiments in assigning all NMR signals to their crystallographically sites is also demonstrated.
