Materials Data on DyNiGe2 by Materials Project

Abstract

DyNiGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Dy is bonded in a 8-coordinate geometry to four equivalent Ni and ten Ge atoms. All Dy–Ni bond lengths are 3.17 Å. There are a spread of Dy–Ge bond distances ranging from 3.09–3.20 Å. Ni is bonded in a 5-coordinate geometry to four equivalent Dy and five Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.29–2.40 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Dy, one Ni, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.49 Å. In the second Ge site, Ge is bonded in a 12-coordinate geometry to four equivalent Dy and four equivalent Ni atoms.
