Title: Materials Data on DyV2(FeCo)5 by Materials Project

Abstract

DyV2(FeCo)5 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. Dy is bonded in a 12-coordinate geometry to two V, ten Fe, and eight Co atoms. There are one shorter (3.00 Å) and one longer (3.02 Å) Dy–V bond lengths. There are a spread of Dy–Fe bond distances ranging from 3.00–3.20 Å. There are six shorter (2.99 Å) and two longer (3.00 Å) Dy–Co bond lengths. There are two inequivalent V sites. In the first V site, V is bonded in a 9-coordinate geometry to one Dy, one V, six Fe, and six Co atoms. The V–V bond length is 2.38 Å. There are four shorter (2.57 Å) and two longer (2.58 Å) V–Fe bond lengths. There are two shorter (2.59 Å) and four longer (2.86 Å) V–Co bond lengths. In the second V site, V is bonded in a 10-coordinate geometry to one Dy, one V, four equivalent Fe, and eight Co atoms. All V–Fe bond lengths are 2.55 Å. There are a spread of V–Co bond distances ranging from 2.58–2.87 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to two equivalent Dy, two V, three Fe, and five Comore » atoms to form distorted FeDy2V2Fe3Co5 cuboctahedra that share corners with twelve FeDy2V2Fe3Co5 cuboctahedra, edges with five FeDy2V2Fe4Co4 cuboctahedra, and faces with eight FeDy2V2Fe3Co5 cuboctahedra. There are a spread of Fe–Fe bond distances ranging from 2.32–2.41 Å. There are a spread of Fe–Co bond distances ranging from 2.39–2.57 Å. In the second Fe site, Fe is bonded to two equivalent Dy, two equivalent V, four equivalent Fe, and four Co atoms to form distorted FeDy2V2Fe4Co4 cuboctahedra that share corners with eight equivalent FeDy2V2Fe3Co5 cuboctahedra, edges with six FeDy2V2Fe4Co4 cuboctahedra, and faces with eight equivalent FeDy2V2Fe3Co5 cuboctahedra. There are two shorter (2.58 Å) and two longer (2.66 Å) Fe–Co bond lengths. There are three inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to two equivalent Dy, two V, five Fe, and three Co atoms. There are two shorter (2.58 Å) and one longer (2.66 Å) Co–Co bond lengths. In the second Co site, Co is bonded in a 12-coordinate geometry to two equivalent Dy, two equivalent V, four equivalent Fe, and four Co atoms. Both Co–Co bond lengths are 2.61 Å. In the third Co site, Co is bonded in a 7-coordinate geometry to one Dy, four V, five Fe, and four Co atoms. The Co–Co bond length is 2.36 Å.« less
