Materials Data on Dy12Co5Bi by Materials Project

Abstract

Dy12Co5Bi crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 5-coordinate geometry to four Co and one Bi atom. There are a spread of Dy–Co bond distances ranging from 2.87–3.24 Å. The Dy–Bi bond length is 3.61 Å. In the second Dy site, Dy is bonded in a 4-coordinate geometry to three Co and one Bi atom. There are one shorter (2.67 Å) and two longer (2.84 Å) Dy–Co bond lengths. The Dy–Bi bond length is 3.43 Å. In the third Dy site, Dy is bonded in a 4-coordinate geometry to three Co and one Bi atom. There are a spread of Dy–Co bond distances ranging from 2.67–3.35 Å. The Dy–Bi bond length is 3.39 Å. There are three inequivalent Co sites. In the first Co site, Co is bonded in a 9-coordinate geometry to eight Dy and one Co atom. The Co–Co bond length is 2.35 Å. In the second Co site, Co is bonded in a 2-coordinate geometry to eight Dy and one Co atom. The Co–Co bond length is 2.20 Å. In the third Co site, Co is bonded in a distorted body-centered cubic geometry to eight Dy atoms. Bi is bonded in a cuboctahedral geometry to twelve Dy atoms.
