Materials Data on Tb3Mn3Ga2Si by Materials Project
Tb3Mn3Ga2Si crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Tb is bonded in a 5-coordinate geometry to six equivalent Mn, four equivalent Ga, and one Si atom. There are four shorter (3.19 Å) and two longer (3.34 Å) Tb–Mn bond lengths. All Tb–Ga bond lengths are 2.93 Å. The Tb–Si bond length is 2.89 Å. Mn is bonded in a 12-coordinate geometry to six equivalent Tb, two equivalent Mn, two equivalent Ga, and two equivalent Si atoms. Both Mn–Mn bond lengths are 2.72 Å. Both Mn–Ga bond lengths are 2.88 Å. Both Mn–Si bond lengths are 2.52 Å. Ga is bonded in a 9-coordinate geometry to six equivalent Tb and three equivalent Mn atoms. Si is bonded in a 9-coordinate geometry to three equivalent Tb and six equivalent Mn atoms.
