Materials Data on GaFeGe by Materials Project
FeGaGe crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Fe is bonded in a 10-coordinate geometry to two equivalent Fe, four equivalent Ga, and four equivalent Ge atoms. Both Fe–Fe bond lengths are 2.52 Å. There are two shorter (2.58 Å) and two longer (2.63 Å) Fe–Ga bond lengths. There are two shorter (2.44 Å) and two longer (2.49 Å) Fe–Ge bond lengths. Ga is bonded in a 9-coordinate geometry to four equivalent Fe, three equivalent Ga, and two equivalent Ge atoms. There are one shorter (2.73 Å) and two longer (2.82 Å) Ga–Ga bond lengths. Both Ga–Ge bond lengths are 3.02 Å. Ge is bonded in a 4-coordinate geometry to four equivalent Fe and two equivalent Ga atoms.
