Materials Data on GaAg2 by Materials Project
Ag2Ga is zeta silver zinc structured and crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are two inequivalent Ag sites. In the first Ag site, Ag is bonded to eight Ag and four Ga atoms to form a mixture of distorted corner, edge, and face-sharing AgGa4Ag8 cuboctahedra. There are a spread of Ag–Ag bond distances ranging from 2.93–3.03 Å. There are two shorter (2.74 Å) and two longer (2.82 Å) Ag–Ga bond lengths. In the second Ag site, Ag is bonded in a 1-coordinate geometry to eight Ag and five Ga atoms. Both Ag–Ag bond lengths are 2.93 Å. There are one shorter (2.85 Å) and four longer (2.92 Å) Ag–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 11-coordinate geometry to nine Ag and two equivalent Ga atoms. Both Ga–Ga bond lengths are 2.93 Å. In the second Ga site, Ga is bonded in a 11-coordinate geometry to nine Ag and two equivalent Ga atoms. Both Ga–Ga bond lengths are 2.93 Å.
