Materials Data on ErGaAu by Materials Project
ErAuGa crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Er is bonded in a 12-coordinate geometry to six equivalent Au and six equivalent Ga atoms. There are a spread of Er–Au bond distances ranging from 3.05–3.22 Å. There are a spread of Er–Ga bond distances ranging from 3.11–3.27 Å. Au is bonded in a 2-coordinate geometry to six equivalent Er, one Au, and three equivalent Ga atoms. The Au–Au bond length is 2.83 Å. There are two shorter (2.60 Å) and one longer (2.90 Å) Au–Ga bond lengths. Ga is bonded in a 10-coordinate geometry to six equivalent Er, three equivalent Au, and one Ga atom. The Ga–Ga bond length is 2.56 Å.
