The study of a layered crystalline Sn(IV) phosphate by solid-state NMR has demonstrated that the 31P T1 relaxation of phosphate groups, dependent on spinning rate is completely controlled by the limited spin diffusion to paramagnetic ions found by EPR. The spin-diffusion constant, D(SD), was estimated as 2.04 10–14 cm2s–1. Finally, the conclusion was supported by the 31P T1 time measurements in zirconium phosphate 1–1, also showing paramagnetic ions and in diamagnetic compound (NH4)2HPO4.
