Abstract:The phosphorus chemical shift anisotropies, 31 PΔcs, and asymmetry parameters η were measured by the 31 P{ 1 H} NMR experiments in static and lowfrequency spinning samples of the zirconium phosphates and phosphonates and also in the mixed Zr (IV)/Sn (IV) phosphate/phosphonate material. The data obtained have shown a 111 connectivity in the HPO 4 and PO 3 groups, which does not change at modification and intercalation of the materials. The 31 PΔcs values of the phosphonate groups (43-49 ppm) significantly surpa… Show more
