Ab initio constrained crystal-chemical Rietveld refinement of Ca₁₀(V_xP_1 − xO₄)₆F₂ apatites

Extraction of reliable bond distances and angles for Ca₁₀(V_xP_1 − xO₄)₆F₂ apatites using standard Rietveld refinement with Cu Kα X-ray powder data was significantly impaired by large imprecision for the O-atom coordinates. An initial attempt to apply crystal-chemical Rietveld refinements to the same compounds was partly successful, and exposed the problematic determination of two oxygen–metal–oxygen angles. Ab initio modeling with VASP in space groups P6₃/m, P2₁/m and Pm showed that both these angular parameters exhibited a linear dependence with the vanadium content. Stable crystal-chemical Rietveld refinements in agreement with quantum results were obtained by fixing these angles at the values from ab initio simulations. Residuals were comparable with the less precise standard refinements. The larger vanadium ion is accommodated primarily by uniform expansion and rotation of BO₄ tetrahedra combined with a rotation of the Ca–Ca–Ca triangular units. It is proposed that the reduction of symmetry for the vanadium end-member is necessary to avoid considerable departures from formal valences at the A^II and B sites in P6₃/m. The complementarity of quantum methods and structural analysis by powder diffraction in cases with problematic least-squares extraction of the crystal chemistry is discussed.

Keywords: apatite; crystal chemistry; ab initio calculations; X-ray powder diffraction; Rietveld refinement; crystal-chemical constraints.
