Materials Data on HoNiGe2 by Materials Project

Abstract

HoNiGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ho is bonded in a 8-coordinate geometry to four equivalent Ni and ten Ge atoms. All Ho–Ni bond lengths are 3.14 Å. There are a spread of Ho–Ge bond distances ranging from 3.12–3.23 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Ho and five Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.29–2.41 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Ho and four equivalent Ni atoms. In the second Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Ho, one Ni, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.50 Å.
