Materials Data on ErNiGe2 by Materials Project

Abstract

ErNiGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Er is bonded in a 8-coordinate geometry to four equivalent Ni and ten Ge atoms. All Er–Ni bond lengths are 3.14 Å. There are a spread of Er–Ge bond distances ranging from 3.09–3.21 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Er and five Ge atoms. There are one shorter (2.29 Å) and four longer (2.39 Å) Ni–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Er, one Ni, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.50 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Er and four equivalent Ni atoms.
