Materials Data on EuGaGe by Materials Project
EuGaGe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Eu sites. In the first Eu site, Eu is bonded to six equivalent Ge atoms to form distorted edge-sharing EuGe6 octahedra. All Eu–Ge bond lengths are 3.19 Å. In the second Eu site, Eu is bonded in a 12-coordinate geometry to six equivalent Ga and six equivalent Ge atoms. All Eu–Ga bond lengths are 3.08 Å. All Eu–Ge bond lengths are 3.49 Å. Ga is bonded in a 6-coordinate geometry to three equivalent Eu and three equivalent Ge atoms. All Ga–Ge bond lengths are 2.56 Å. Ge is bonded in a 6-coordinate geometry to six Eu and three equivalent Ga atoms.
