Figure 6
Part of the NaSICON structure of Ag₃Sc₂(PO₄)₃ at 298 K (R $[\overline{3}]$ c), viewed along [100], showing a lantern unit and some neighbouring polyhedra for γ-ASP. The atom nomenclature and equivalent atoms are as in the text. [Symmetry codes: (i) −y + 1, x − y, z; (ii) −y, x − y, z; (iii) y − 1, x, −z + $[1 \over 2]$ ; (iv) x − y, −y, −z + $[1 \over 2]$ ; (v) −x + $[1 \over 3]$ , −y − $[1 \over 3]$ , −z + $[2 \over 3]$ ; (vi) −x + $[1 \over 3]$ , −y + $[2 \over 3]$ , −z + $[2 \over 3]$ ; (vii) y, x, −z + $[1 \over 2]$ ; (viii) −y + $[1 \over 3]$ , −x + $[2 \over 3]$ , z + $[1 \over 6]$ ; (ix) −x + y + $[1 \over 3]$ , y + $[2 \over 3]$ , z + $[1 \over 6]$ ; (x) −x + $[1 \over 3]$ , −x + y − $[1 \over 3]$ , −z + $[1 \over 6]$ ; (xi) x − y, x, −z; (xii) −x + y, −x, z; (xiii) −x − 1, −x, z; (xiv) x, y − 1, z; (xv) y, −x + y, −z; (xvi) y − $[1 \over 3]$ , −x + y + $[1 \over 3]$ , −z + $[1 \over 3]$ .]
