Materials Data on Y2Ga3Ag by Materials Project
Y2AgGa3 crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 12-coordinate geometry to three equivalent Ag and nine Ga atoms. All Y–Ag bond lengths are 3.02 Å. There are a spread of Y–Ga bond distances ranging from 3.03–3.43 Å. In the second Y site, Y is bonded in a 12-coordinate geometry to three equivalent Ag and nine Ga atoms. All Y–Ag bond lengths are 3.27 Å. There are a spread of Y–Ga bond distances ranging from 3.02–3.41 Å. Ag is bonded in a 10-coordinate geometry to six Y and four Ga atoms. There are three shorter (2.64 Å) and one longer (3.07 Å) Ag–Ga bond lengths. There are three inequivalent Ga sites. In the first Ga site, Ga is bonded in a 10-coordinate geometry to six Y, three equivalent Ag, and one Ga atom. The Ga–Ga bond length is 3.06 Å. In the second Ga site, Ga is bonded in a 10-coordinate geometry to six Y and four Ga atoms. All Ga–Ga bond lengths are 2.69 Å. In the third Ga site, Ga is bonded in a 10-coordinate geometry to six Y, one Ag, and three equivalent Ga atoms.
