Materials Data on Dy12Co7 by Materials Project

Abstract

Dy12Co7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are six inequivalent Dy sites. In the first Dy site, Dy is bonded in a 4-coordinate geometry to four Co atoms. There are a spread of Dy–Co bond distances ranging from 2.76–2.96 Å. In the second Dy site, Dy is bonded in a 4-coordinate geometry to four Co atoms. There are a spread of Dy–Co bond distances ranging from 2.80–3.04 Å. In the third Dy site, Dy is bonded to four Co atoms to form distorted corner-sharing DyCo4 tetrahedra. There are a spread of Dy–Co bond distances ranging from 2.71–3.00 Å. In the fourth Dy site, Dy is bonded in a 5-coordinate geometry to five Co atoms. There are a spread of Dy–Co bond distances ranging from 2.81–3.39 Å. In the fifth Dy site, Dy is bonded in a 5-coordinate geometry to five Co atoms. There are a spread of Dy–Co bond distances ranging from 2.74–3.12 Å. In the sixth Dy site, Dy is bonded in a 5-coordinate geometry to five Co atoms. There are a spread of Dy–Co bond distances ranging from 2.89–3.09 Å. There are four inequivalent Co sites. In the first Co site, Co is bonded in a body-centered cubic geometry to eight Dy atoms. In the second Co site, Co is bonded in a 10-coordinate geometry to seven Dy and one Co atom. The Co–Co bond length is 2.31 Å. In the third Co site, Co is bonded in a 9-coordinate geometry to eight Dy and one Co atom. In the fourth Co site, Co is bonded in a 8-coordinate geometry to eight Dy atoms.
