Materials Data on ScSiPt2 by Materials Project
ScPt2Si crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sc2+ is bonded in a 3-coordinate geometry to three equivalent Si4- atoms. There are one shorter (2.79 Å) and two longer (2.86 Å) Sc–Si bond lengths. Pt1+ is bonded in a trigonal non-coplanar geometry to three equivalent Si4- atoms. There are one shorter (2.45 Å) and two longer (2.52 Å) Pt–Si bond lengths. Si4- is bonded in a 9-coordinate geometry to three equivalent Sc2+ and six equivalent Pt1+ atoms.
