Materials Data on LiSiPt2 by Materials Project
LiPt2Si is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of four lithium molecules and one Pt2Si framework. In the Pt2Si framework, Pt+1.50+ is bonded to four equivalent Si4- atoms to form a mixture of corner and edge-sharing PtSi4 tetrahedra. All Pt–Si bond lengths are 2.58 Å. Si4- is bonded in a distorted body-centered cubic geometry to eight equivalent Pt+1.50+ atoms.
