Crystal structure of a silver-, cobalt- and iron-based phosphate with an alluaudite-like structure: Ag_1.655Co_1.64Fe_1.36(PO₄)₃.

ABSTRACT: The new silver-, cobalt- and iron-based phosphate, silver cobalt iron tris(ortho-phosphate), Ag_1.655Co_1.64Fe_1.36(PO₄)₃, was synthesized by solid-state reactions. Its structure is isotypic to that of Na₂Co₂Fe(PO₄)₃, and belongs to the alluaudite family, with a partial cationic disorder, the Ag^I atoms being located on an inversion centre and twofold rotation axis sites (Wyckoff positions 4a and 4e), with partial occupancies of 0.885 (2) and 0.7688 (19), respectively. One of the two P atoms in the asymmetric unit completely fills one 4e site while the Co and Fe atoms fill another 4e site, with partial occupancies of 0.86 (5) and 0.14 (5), respectively. The
