Materials Data on Y3Co2 by Materials Project
Y3Co2 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are three inequivalent Y sites. In the first Y site, Y is bonded in a 4-coordinate geometry to five Co atoms. There are a spread of Y–Co bond distances ranging from 2.81–3.66 Å. In the second Y site, Y is bonded in a distorted trigonal non-coplanar geometry to three Co atoms. There are two shorter (2.74 Å) and one longer (3.07 Å) Y–Co bond lengths. In the third Y site, Y is bonded in a 7-coordinate geometry to seven Co atoms. There are a spread of Y–Co bond distances ranging from 2.91–3.22 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 9-coordinate geometry to eight Y and one Co atom. The Co–Co bond length is 2.37 Å. In the second Co site, Co is bonded in a 9-coordinate geometry to seven Y and two Co atoms. The Co–Co bond length is 2.41 Å.
