Materials Data on Y3Ge5 by Materials Project

Y3Ge5 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first 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 2.98–3.09 Å. In the second Y site, Y is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Y–Ge bond distances ranging from 2.95–3.50 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to five Y and two equivalent Ge atoms. There are one shorter (2.59 Å) and one longer (2.66 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Y and three Ge atoms. The Ge–Ge bond length is 2.60 Å. In the third Ge site, Ge is bonded in a 8-coordinate geometry to six Y and two equivalent Ge atoms.
