Materials Data on YGe3 by Materials Project

Abstract

YGe3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Y is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Y–Ge bond distances ranging from 2.97–3.26 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Y and five equivalent Ge atoms. There are one shorter (2.51 Å) and four longer (2.83 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Y and five equivalent Ge atoms. In the third Ge site, Ge is bonded in a 8-coordinate geometry to six equivalent Y and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.57 Å.
