Materials Data on YbSiPt2 by Materials Project
YbPt2Si crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Yb2+ is bonded in a 3-coordinate geometry to three equivalent Si4- atoms. There are one shorter (2.95 Å) and two longer (2.97 Å) Yb–Si bond lengths. Pt1+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent Si4- atoms. There are a spread of Pt–Si bond distances ranging from 2.47–2.57 Å. Si4- is bonded in a 9-coordinate geometry to three equivalent Yb2+ and six equivalent Pt1+ atoms.
