Title: Materials Data on Y2CoNi5 by Materials Project

Abstract

Y2CoNi5 crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are six inequivalent Y sites. In the first Y site, Y is bonded in a 12-coordinate geometry to three equivalent Co and nine Ni atoms. All Y–Co bond lengths are 2.94 Å. There are six shorter (2.86 Å) and three longer (3.08 Å) Y–Ni bond lengths. In the second Y site, Y is bonded in a 12-coordinate geometry to three equivalent Co and nine Ni atoms. All Y–Co bond lengths are 2.95 Å. There are six shorter (2.86 Å) and three longer (3.07 Å) Y–Ni bond lengths. In the third Y site, Y is bonded in a 12-coordinate geometry to three equivalent Co and nine Ni atoms. All Y–Co bond lengths are 2.94 Å. There are six shorter (2.86 Å) and three longer (3.07 Å) Y–Ni bond lengths. In the fourth Y site, Y is bonded in a 12-coordinate geometry to three equivalent Co and nine Ni atoms. All Y–Co bond lengths are 2.94 Å. There are six shorter (2.86 Å) and three longer (3.08 Å) Y–Ni bond lengths. In the fifth Y site, Y is bonded in a 6-coordinate geometry to three equivalent Co and fifteenmore » Ni atoms. All Y–Co bond lengths are 2.87 Å. There are three shorter (2.87 Å) and twelve longer (3.18 Å) Y–Ni bond lengths. In the sixth Y site, Y is bonded in a distorted hexagonal planar geometry to eighteen Ni atoms. There are a spread of Y–Ni bond distances ranging from 2.87–3.19 Å. There are three inequivalent Co sites.

All Ni–Ni bond lengths are 2.44 Å. In the fourth Ni site, Ni is bonded in a 12-coordinate geometry to three equivalent Y and six Ni atoms. All Ni–Ni bond lengths are 2.45 Å. In the fifth Ni site, Ni is bonded in a 12-coordinate geometry to three equivalent Y and six Ni atoms. All Ni–Ni bond lengths are 2.46 Å.

There are two shorter (2.48 Å) and two longer (2.49 Å) Ni–Ni bond lengths. In the seventh Ni site, Ni is bonded to five Y, two Co, and five Ni atoms to form NiY5Co2Ni5 cuboctahedra that share corners with four CoY3Ni9 cuboctahedra, corners with seventeen NiY5Co2Ni5 cuboctahedra, edges with eight NiY5Co2Ni5 cuboctahedra, faces with six CoY3Ni9 cuboctahedra, and faces with fourteen NiY5Co2Ni5 cuboctahedra.
