Materials Data on ErGaAg by Materials Project

Abstract

ErAgGa crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Er is bonded in a 12-coordinate geometry to six equivalent Ag and six equivalent Ga atoms. There are a spread of Er–Ag bond distances ranging from 3.10–3.28 Å. There are a spread of Er–Ga bond distances ranging from 3.12–3.24 Å. Ag is bonded in a 10-coordinate geometry to six equivalent Er, one Ag, and three equivalent Ga atoms. The Ag–Ag bond length is 2.78 Å. There are two shorter (2.62 Å) and one longer (2.88 Å) Ag–Ga bond lengths. Ga is bonded in a 10-coordinate geometry to six equivalent Er, three equivalent Ag, and one Ga atom. The Ga–Ga bond length is 2.57 Å.
