Materials Data on Er3Mn3Ga2Si by Materials Project
Er3Mn3Ga2Si 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 Si atom. There are four shorter (3.16 Å) and two longer (3.27 Å) Er–Mn bond lengths. All Er–Ga bond lengths are 2.89 Å. The Er–Si bond length is 2.86 Å. Mn is bonded in a 12-coordinate geometry to six equivalent Er, two equivalent Mn, two equivalent Ga, and two equivalent Si atoms. Both Mn–Mn bond lengths are 2.68 Å. Both Mn–Ga bond lengths are 2.83 Å. Both Mn–Si bond lengths are 2.49 Å. Ga is bonded in a 9-coordinate geometry to six equivalent Er and three equivalent Mn atoms. Si is bonded in a 9-coordinate geometry to three equivalent Er and six equivalent Mn atoms.
