Materials Data on TbSiPt2 by Materials Project
TbPt2Si crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tb4+ is bonded in a 7-coordinate geometry to four equivalent Pt and three equivalent Si4- atoms. There are two shorter (3.00 Å) and two longer (3.01 Å) Tb–Pt bond lengths. There are a spread of Tb–Si bond distances ranging from 2.99–3.02 Å. Pt is bonded in a 3-coordinate geometry to two equivalent Tb4+ and three equivalent Si4- atoms. There are a spread of Pt–Si bond distances ranging from 2.50–2.63 Å. Si4- is bonded in a 9-coordinate geometry to three equivalent Tb4+ and six equivalent Pt atoms.
