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. 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.
