Abstract

Two solid solutions BiM_xMg_2-x)PO₆ (with M²⁺ = Zn or Cd) have been studied through ³¹P MAS NMR. The analysis has been performed on the basis of refined crystal structures through X-ray diffraction and neutron diffraction. The BiZn_xMg_(2-x)PO₆ does not provide direct evidence for sensitive changes in the phosphorus local symmetry. This result is in good agreement with structural data which show nearly unchanged lattices and atomic separations through the Zn²⁺ for Mg²⁺ substitution. On the other hand, the Cd²⁺ for Mg²⁺ substitution behaves differently. Indeed, up to five resonances are observed, each corresponding to one of the five first-cationic neighbour distributions, i.e. 4Mg/0Cd, 3Mg/lCd, 2Mg/2Cd, 1Mg/3Cd and 0Mg/4Cd. Their intensities match rather well the expected weight for each configuration of the statistical Cd²⁺/Mg²⁺ mixed occupancy. The match is further improved when one takes into account the influence of the 2nd cationic sphere that is available from high-field NMR data (18.8T). Finally, the fine examination of the chemical shift for each resonance versus x allows to de-convolute the mean Z/a² effective field into two sub-effects: a lattice constraint-only term and a chemical-only term whose effects are directly quantifiable.

PO<sub>6</sub>
 (with M<sup>2+</sup>

P MAS NMR. The analysis has been performed on the basis of refined crystal structures through X-ray diffraction and neutron diffraction. The BiZn<sub>x</sub>
Mg<sub>(2-x</sub>

 does not provide direct evidence for sensitive changes in the phosphorus local symmetry. This result is in good agreement with structural data which show nearly unchanged lattices and atomic separations through the Zn<sup>2+</sup>
 for Mg<sup>2+</sup>
 substitution. On the other hand, the Cd<sup>2+</sup>
 for Mg<sup>2+</sup>
 substitution behaves differently. Indeed, up to five resonances are observed, each corresponding to one of the five first-cationic neighbour distributions, i.e. 4Mg/0Cd, 3Mg/lCd, 2Mg/2Cd, 1Mg/3Cd and 0Mg/4Cd. Their intensities match rather well the expected weight for each configuration of the statistical Cd<sup>2+</sup>
/Mg<sup>2+</sup>
 mixed occupancy. The match is further improved when one takes into account the influence of the 2nd cationic sphere that is available from high-field NMR data (18.8T). Finally, the fine examination of the chemical shift for each resonance versus x allows to de-convolute the mean Z/a<sup>2</sup>
 effective field into two sub-effects: a lattice constraint-only term and a chemical-only term whose effects are directly quantifiable.</s0>
