Figure 1 Partial plot of AgMg₃(PO₄)(HPO₄)₂ crystal structure. Displacement ellipsoids are drawn at the 50% probability level. Only the major component of the disordered silver atom is shown. Symmetry codes: (i) −x + $[{1\over 2}]$ , y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (ii) x + $[{1\over 2}]$ , y − $[{1\over 2}]$ , z + 1; (iii) x + $[{1\over 2}]$ , −y + $[{1\over 2}]$ , z + $[{1\over 2}]$ ; (iv) −x + $[{1\over 2}]$ , −y + $[{1\over 2}]$ , −z + 1; (v) −x + 1, y, −z + $[{3\over 2}]$ ; (vi) −x + 1, −y, −z + 1; (vii) −x + 1, −y, −z + 2; (viii) x + $[{1\over 2}]$ , −y + $[{1\over 2}]$ , z − $[{1\over 2}]$ ; (ix) −x + $[{1\over 2}]$ , −y + $[{1\over 2}]$ , −z; (x) −x + 1, y, −z + $[{1\over 2}]$ ; (xi) −x, y, −z + $[{1\over 2}]$ ; (xii) −x + $[{1\over 2}]$ , y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (xiii) x − $[{1\over 2}]$ , y + $[{1\over 2}]$ , z − 1.
