Materials Data on InAg3(PO4)2 by Materials Project

Abstract

Ag3In(PO4)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ag–O bond distances ranging from 2.32–2.97 Å. In the second Ag1+ site, Ag1+ is bonded to six O2- atoms to form distorted AgO6 octahedra that share corners with six equivalent PO4 tetrahedra and edges with two equivalent InO6 octahedra. There are two shorter (2.25 Å) and four longer (2.77 Å) Ag–O bond lengths. In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with six equivalent PO4 tetrahedra and edges with two equivalent AgO6 octahedra. There are two shorter (2.16 Å) and four longer (2.19 Å) In–O bond lengths. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent AgO6 octahedra and corners with three equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 40–56°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to four Ag1+ and one P5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Ag1+, one In3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Ag1+, one In3+, and one P5+ atom.
