Materials Data on TbScSi2 by Materials Project
TbScSi2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Tb is bonded in a 5-coordinate geometry to seven Si atoms. There are a spread of Tb–Si bond distances ranging from 2.88–3.08 Å. Sc is bonded in a 5-coordinate geometry to seven Si atoms. There are a spread of Sc–Si bond distances ranging from 2.88–3.04 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to three equivalent Tb, four equivalent Sc, and two equivalent Si atoms. Both Si–Si bond lengths are 2.47 Å. In the second Si site, Si is bonded in a 9-coordinate geometry to four equivalent Tb, three equivalent Sc, and two equivalent Si atoms.
