Materials Data on Dy3(Co2Sn)4 by Materials Project
Abstract
Dy3Co8Sn4 is Hexagonal Laves-derived structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Dy is bonded in a 12-coordinate geometry to six Co and six Sn atoms. There are a spread of Dy–Co bond distances ranging from 3.03–3.36 Å. There are a spread of Dy–Sn bond distances ranging from 3.17–3.26 Å. There are four inequivalent Co sites. In the first Co site, Co is bonded in a 10-coordinate geometry to six equivalent Dy and four Sn atoms. There are three shorter (2.52 Å) and one longer (2.64 Å) Co–Sn bond lengths. In the second Co site, Co is bonded to two equivalent Dy, seven Co, and three equivalent Sn atoms to form distorted CoDy2Co7Sn3 cuboctahedra that share corners with four equivalent CoDy2Co7Sn3 cuboctahedra, corners with five equivalent SnDy4Co8 cuboctahedra, faces with six equivalent SnDy4Co8 cuboctahedra, and faces with eight CoDy2Co7Sn3 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.37–2.60 Å. There are one shorter (2.63 Å) and two longer (2.65 Å) Co–Sn bond lengths. In the third Co site, Co is bonded in a 12-coordinate geometry to two equivalent Dy, four Co, and four Sn atoms. The Co–Co bond length is 2.49 Å.more »
