Materials Data on Tm3Mn3Ga2Si by Materials Project

Abstract

Tm3Mn3Ga2Si crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Tm is bonded in a 5-coordinate geometry to six equivalent Mn, four equivalent Ga, and one Si atom. There are four shorter (3.13 Å) and two longer (3.26 Å) Tm–Mn bond lengths. All Tm–Ga bond lengths are 2.88 Å. The Tm–Si bond length is 2.84 Å. Mn is bonded in a 12-coordinate geometry to six equivalent Tm, two equivalent Mn, two equivalent Ga, and two equivalent Si atoms. Both Mn–Mn bond lengths are 2.70 Å. Both Mn–Ga bond lengths are 2.82 Å. Both Mn–Si bond lengths are 2.48 Å. Ga is bonded in a 9-coordinate geometry to six equivalent Tm and three equivalent Mn atoms. Si is bonded in a 9-coordinate geometry to three equivalent Tm and six equivalent Mn atoms.
