Materials Data on Y5(CoTe)2 by Materials Project
Y5(CoTe)2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are three inequivalent Y sites. In the first Y site, Y is bonded in a 7-coordinate geometry to three Co and four equivalent Te atoms. There are one shorter (2.83 Å) and two longer (2.84 Å) Y–Co bond lengths. There are two shorter (3.33 Å) and two longer (3.35 Å) Y–Te bond lengths. In the second Y site, Y is bonded in a 6-coordinate geometry to three Co and three equivalent Te atoms. There are two shorter (2.85 Å) and one longer (2.92 Å) Y–Co bond lengths. There are one shorter (3.15 Å) and two longer (3.20 Å) Y–Te bond lengths. In the third Y site, Y is bonded in a distorted square co-planar geometry to two Co and two equivalent Te atoms. There are one shorter (2.95 Å) and one longer (3.26 Å) Y–Co bond lengths. Both Y–Te bond lengths are 3.18 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 9-coordinate geometry to seven Y and two equivalent Co atoms. Both Co–Co bond lengths are 2.38 Å. In the second Co site, Co is bonded in a 9-coordinate geometry to seven Y and two equivalent Co atoms. Te is bonded in a 8-coordinate geometry to eight Y atoms.
