Materials Data on MgGaPt2 by Materials Project

MgPt2Ga is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Mg2+ is bonded in a body-centered cubic geometry to eight equivalent Pt2- atoms. All Mg–Pt bond lengths are 2.72 Å. Pt2- is bonded in a body-centered cubic geometry to four equivalent Mg2+ and four equivalent Ga2+ atoms. All Pt–Ga bond lengths are 2.72 Å. Ga2+ is bonded in a body-centered cubic geometry to eight equivalent Pt2- atoms.

Materials Data on MgGaPt2 by Materials Project

MgPt2Ga crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two MgPt2Ga ribbons oriented in the (1, 0, 0) direction. Mg2+ is bonded in a linear geometry to two equivalent Pt2- atoms. Both Mg–Pt bond lengths are 2.48 Å. Pt2- is bonded in a linear geometry to one Mg2+ and one Ga2+ atom. The Pt–Ga bond length is 2.31 Å. Ga2+ is bonded in a linear geometry to two equivalent Pt2- atoms.
