Materials Data on Th2(FeCo)5 by Materials Project
Abstract
Th2(FeCo)5 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are two inequivalent Th sites. In the first Th site, Th is bonded in a 6-coordinate geometry to twelve Fe and six Co atoms. There are a spread of Th–Fe bond distances ranging from 3.20–3.23 Å. There are four shorter (2.84 Å) and two longer (2.93 Å) Th–Co bond lengths. In the second Th site, Th is bonded in a 6-coordinate geometry to eight Fe and ten Co atoms. All Th–Fe bond lengths are 3.18 Å. There are a spread of Th–Co bond distances ranging from 2.88–3.23 Å. There are three inequivalent Fe sites. In the first Fe site, Fe is bonded to four equivalent Th, four Fe, and four equivalent Co atoms to form distorted FeTh4Fe4Co4 cuboctahedra that share corners with four equivalent CoTh4Fe4Co4 cuboctahedra, corners with twelve FeTh4Fe4Co4 cuboctahedra, edges with ten FeTh4Fe4Co4 cuboctahedra, and faces with ten FeTh4Fe4Co4 cuboctahedra. There are two shorter (2.53 Å) and two longer (2.54 Å) Fe–Fe bond lengths. All Fe–Co bond lengths are 2.45 Å. In the second Fe site, Fe is bonded to four Th, three Fe, and five Co atoms to form distorted FeTh4Fe3Co5 cuboctahedra that sharemore »
