Materials Data on ScSiPt by Materials Project
ScPtSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sc2+ is bonded in a 6-coordinate geometry to six equivalent Si4- atoms. There are a spread of Sc–Si bond distances ranging from 2.88–3.15 Å. Pt2+ is bonded to four equivalent Si4- atoms to form a mixture of corner and edge-sharing PtSi4 trigonal pyramids. There are a spread of Pt–Si bond distances ranging from 2.45–2.60 Å. Si4- is bonded in a 4-coordinate geometry to six equivalent Sc2+ and four equivalent Pt2+ atoms.
