Materials Data on Dy3NiGe2 by Materials Project
Dy3NiGe2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 6-coordinate geometry to one Ni and five Ge atoms. The Dy–Ni bond length is 2.84 Å. There are a spread of Dy–Ge bond distances ranging from 2.98–3.19 Å. In the second Dy site, Dy is bonded in a 7-coordinate geometry to two equivalent Ni and five Ge atoms. Both Dy–Ni bond lengths are 2.80 Å. There are a spread of Dy–Ge bond distances ranging from 2.99–3.62 Å. In the third Dy site, Dy is bonded in a 8-coordinate geometry to three equivalent Ni and five Ge atoms. There are one shorter (2.95 Å) and two longer (3.01 Å) Dy–Ni bond lengths. There are a spread of Dy–Ge bond distances ranging from 2.99–3.08 Å. Ni is bonded in a 9-coordinate geometry to six Dy and three Ge atoms. There are one shorter (2.49 Å) and two longer (2.52 Å) Ni–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Dy and two equivalent Ni atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to eight Dy and one Ni atom.
