Materials Data on Y2Co17 by Materials Project
Y2Co17 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 2-coordinate geometry to twenty Co atoms. There are a spread of Y–Co bond distances ranging from 2.91–3.15 Å. In the second Y site, Y is bonded in a 12-coordinate geometry to eighteen Co atoms. There are a spread of Y–Co bond distances ranging from 2.95–3.25 Å. There are four inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to two Y and ten Co atoms. There are a spread of Co–Co bond distances ranging from 2.36–2.67 Å. In the second Co site, Co is bonded to two equivalent Y and ten Co atoms to form CoY2Co10 cuboctahedra that share corners with fourteen CoY3Co9 cuboctahedra, edges with six equivalent CoY3Co9 cuboctahedra, and faces with ten CoY2Co10 cuboctahedra. There are four shorter (2.41 Å) and two longer (2.56 Å) Co–Co bond lengths. In the third Co site, Co is bonded in a 2-coordinate geometry to one Y and thirteen Co atoms. There are one shorter (2.32 Å) and three longer (2.61 Å) Co–Co bond lengths. In the fourth Co site, Co is bonded to three Y and nine Co atoms to form distorted CoY3Co9 cuboctahedra that share corners with fifteen CoY3Co9 cuboctahedra, edges with eight CoY3Co9 cuboctahedra, and faces with ten CoY2Co10 cuboctahedra. Both Co–Co bond lengths are 2.42 Å.
