Materials Data on TmScSi by Materials Project
Abstract
TmScSi is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent Tm sites. In the first Tm site, Tm is bonded in a 7-coordinate geometry to two equivalent Sc and five Si atoms. There are one shorter (3.06 Å) and one longer (3.11 Å) Tm–Sc bond lengths. There are a spread of Tm–Si bond distances ranging from 2.80–3.24 Å. In the second Tm site, Tm is bonded in a 7-coordinate geometry to six Sc and five Si atoms. There are two shorter (2.88 Å) and four longer (3.24 Å) Tm–Sc bond lengths. There are a spread of Tm–Si bond distances ranging from 2.79–3.18 Å. In the third Tm site, Tm is bonded in a 7-coordinate geometry to two equivalent Sc and five Si atoms. Both Tm–Sc bond lengths are 3.17 Å. There are a spread of Tm–Si bond distances ranging from 2.77–3.29 Å. In the fourth Tm site, Tm is bonded to seven Si atoms to form distorted corner-sharing TmSi7 pentagonal bipyramids. There are a spread of Tm–Si bond distances ranging from 2.96–3.29 Å. There are two inequivalent Sc sites. In the first Sc site, Sc is bonded inmore »
