Materials Data on YNiGe2 by Materials Project

Abstract

YNiGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Y is bonded in a 8-coordinate geometry to four equivalent Ni and ten Ge atoms. All Y–Ni bond lengths are 3.17 Å. There are a spread of Y–Ge bond distances ranging from 3.10–3.22 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Y and five Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.29–2.39 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Y, one Ni, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.52 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Y and four equivalent Ni atoms.
