Materials Data on Y3Ge4 by Materials Project
Y3Ge4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 5-coordinate geometry to seven Ge atoms. There are a spread of Y–Ge bond distances ranging from 2.92–3.19 Å. In the second Y site, Y is bonded in a 8-coordinate geometry to eight Ge atoms. There are a spread of Y–Ge bond distances ranging from 3.00–3.11 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Y and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.62 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Y and four equivalent Ge atoms. All Ge–Ge bond lengths are 2.87 Å. In the third Ge site, Ge is bonded in a 9-coordinate geometry to six Y and three Ge atoms.
