Materials Data on Er3Mn3Ga2Ge by Materials Project

Abstract

Er3Mn3GeGa2 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Er is bonded in a 5-coordinate geometry to six equivalent Mn, four equivalent Ga, and one Ge atom. There are two shorter (3.22 Å) and four longer (3.25 Å) Er–Mn bond lengths. All Er–Ga bond lengths are 2.95 Å. The Er–Ge bond length is 2.93 Å. Mn is bonded in a 12-coordinate geometry to six equivalent Er, two equivalent Mn, two equivalent Ga, and two equivalent Ge atoms. Both Mn–Mn bond lengths are 2.87 Å. Both Mn–Ga bond lengths are 2.79 Å. Both Mn–Ge bond lengths are 2.62 Å. Ga is bonded in a 9-coordinate geometry to six equivalent Er and three equivalent Mn atoms. Ge is bonded in a 9-coordinate geometry to three equivalent Er and six equivalent Mn atoms.
