Materials Data on Dy4In(NiGe2)2 by Materials Project

Abstract

Dy4In(NiGe2)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 6-coordinate geometry to three equivalent Ni, two equivalent In, and five Ge atoms. There are one shorter (2.98 Å) and two longer (3.31 Å) Dy–Ni bond lengths. Both Dy–In bond lengths are 3.35 Å. There are a spread of Dy–Ge bond distances ranging from 2.92–3.08 Å. In the second Dy site, Dy is bonded in a 12-coordinate geometry to three equivalent Ni, two equivalent In, and seven Ge atoms. There are two shorter (3.04 Å) and one longer (3.06 Å) Dy–Ni bond lengths. Both Dy–In bond lengths are 3.41 Å. There are a spread of Dy–Ge bond distances ranging from 2.97–3.29 Å. Ni is bonded in a 10-coordinate geometry to six Dy and four Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.39–2.57 Å. In is bonded to eight Dy and four Ge atoms to form face-sharing InDy8Ge4 cuboctahedra. There are two shorter (2.88 Å) and two longer (3.14 Å) In–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Dy, one Ni, one In, and one Ge atom. The Ge–Ge bond length is 2.53 Å. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six Dy, three equivalent Ni, and one In atom.
