Materials Data on Ho3Mn3Ga2Si by Materials Project
Ho3Mn3SiGa2 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ho is bonded in a 5-coordinate geometry to six equivalent Mn, four equivalent Ga, and one Si atom. There are four shorter (3.17 Å) and two longer (3.28 Å) Ho–Mn bond lengths. All Ho–Ga bond lengths are 2.91 Å. The Ho–Si bond length is 2.88 Å. Mn is bonded in a 12-coordinate geometry to six equivalent Ho, two equivalent Mn, two equivalent Ga, and two equivalent Si atoms. Both Mn–Mn bond lengths are 2.69 Å. Both Mn–Ga bond lengths are 2.84 Å. Both Mn–Si bond lengths are 2.50 Å. Ga is bonded in a 9-coordinate geometry to six equivalent Ho and three equivalent Mn atoms. Si is bonded in a 9-coordinate geometry to three equivalent Ho and six equivalent Mn atoms.
