Materials Data on Dy2Co7 by Materials Project
Dy2Co7 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are four inequivalent Dy sites. In the first Dy site, Dy is bonded in a 6-coordinate geometry to eighteen Co atoms. There are a spread of Dy–Co bond distances ranging from 2.86–3.23 Å. In the second Dy site, Dy is bonded in a 12-coordinate geometry to twelve Co atoms. There are a spread of Dy–Co bond distances ranging from 2.86–3.10 Å. In the third Dy site, Dy is bonded in a 6-coordinate geometry to eighteen Co atoms. There are a spread of Dy–Co bond distances ranging from 2.86–3.23 Å. In the fourth Dy site, Dy is bonded in a 6-coordinate geometry to eighteen Co atoms. There are a spread of Dy–Co bond distances ranging from 2.86–3.23 Å. There are eight inequivalent Co sites. In the first Co site, Co is bonded to four Dy and eight Co atoms to form CoDy4Co8 cuboctahedra that share corners with sixteen CoDy4Co8 cuboctahedra, edges with ten CoDy4Co8 cuboctahedra, and faces with ten CoDy5Co7 cuboctahedra. Both Co–Dy bond lengths are 3.10 Å. There are a spread of Co–Co bond distances ranging from 2.44–2.47 Å. In the second Co site, Co is bonded to six equivalent Dy and six equivalent Co atoms to form CoDy6Co6 cuboctahedra that share corners with twelve equivalent CoDy5Co7 cuboctahedra, edges with six equivalent CoDy6Co6 cuboctahedra, and faces with eighteen equivalent CoDy5Co7 cuboctahedra. All Co–Co bond lengths are 2.53 Å. In the third Co site, Co is bonded in a 12-coordinate geometry to three equivalent Dy and six Co atoms. All Co–Co bond lengths are 2.43 Å. In the fourth Co site, Co is bonded in a 12-coordinate geometry to three equivalent Dy and six Co atoms. There are three shorter (2.42 Å) and three longer (2.45 Å) Co–Co bond lengths. In the fifth Co site, Co is bonded to four Dy and eight Co atoms to form a mixture of edge, corner, and face-sharing CoDy4Co8 cuboctahedra. There are two shorter (2.44 Å) and four longer (2.47 Å) Co–Co bond lengths. In the sixth Co site, Co is bonded to four Dy and eight Co atoms to form a mixture of edge, corner, and face-sharing CoDy4Co8 cuboctahedra. Both Co–Co bond lengths are 2.44 Å. In the seventh Co site, Co is bonded to five Dy and seven Co atoms to form distorted CoDy5Co7 cuboctahedra that share corners with seventeen CoDy6Co6 cuboctahedra, edges with eight CoDy4Co8 cuboctahedra, and faces with fourteen CoDy6Co6 cuboctahedra. All Co–Co bond lengths are 2.47 Å. In the eighth Co site, Co is bonded to four Dy and eight Co atoms to form CoDy4Co8 cuboctahedra that share corners with sixteen CoDy5Co7 cuboctahedra, edges with ten CoDy4Co8 cuboctahedra, and faces with ten CoDy4Co8 cuboctahedra. Both Co–Dy bond lengths are 3.10 Å. There are a spread of Co–Co bond distances ranging from 2.44–2.47 Å.
