Synthesis, crystal structure determination of a novel phosphate Ag_1.64Zn_1.64Fe_1.36(PO₄)₃ with an alluaudite-like structure.

ABSTRACT: Single crystals of Ag_1.64Zn_1.64Fe_1.36(PO₄)₃ [silver zinc iron phosphate (1.64/1.64/1.36/3)] have been synthesized by a conventional solid-state reaction and structurally characterized by single-crystal X-ray diffraction. The title compound crystallizes with an alluaudite-like structure. All atoms of the structure are in general positions except for four, which reside on special positions of the space group, C2/c. The Ag⁺ cations reside at full occupancy on inversion centre sites and at partial occupancy (64%) on a twofold rotation axis. In this structure, the unique Fe³⁺ ion with one of the two Zn²⁺ cations are substitutionally disordered on the same general position (Wyckoff site 8f
