Materials Data on Y2(Ga3Co)3 by Materials Project
Y2Co3Ga9 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Y is bonded in a 11-coordinate geometry to eleven Ga atoms. There are a spread of Y–Ga bond distances ranging from 2.97–3.04 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to eight Ga atoms. There are a spread of Co–Ga bond distances ranging from 2.51–2.56 Å. In the second Co site, Co is bonded in a 12-coordinate geometry to eight Ga atoms. There are four shorter (2.53 Å) and four longer (2.55 Å) Co–Ga bond lengths. There are four inequivalent Ga sites. In the first Ga site, Ga is bonded in a 11-coordinate geometry to three equivalent Y, three Co, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.74–2.82 Å. In the second Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Y, three Co, and five Ga atoms. There are one shorter (2.68 Å) and two longer (2.81 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Y, two equivalent Co, and six Ga atoms. Both Ga–Ga bond lengths are 2.74 Å. In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Y, two equivalent Co, and six Ga atoms. The Ga–Ga bond length is 2.72 Å.
