Materials Data on Dy(GeRh)2 by Materials Project

Dy(RhGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Dy is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Ge atoms. All Dy–Rh bond lengths are 3.32 Å. All Dy–Ge bond lengths are 3.19 Å. Rh is bonded to four equivalent Dy and four equivalent Ge atoms to form a mixture of distorted edge, face, and corner-sharing RhDy4Ge4 tetrahedra. All Rh–Ge bond lengths are 2.46 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Dy, four equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.52 Å.

Materials Data on Dy3(GeRh)2 by Materials Project

Dy3(RhGe)2 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 9-coordinate geometry to four equivalent Rh and five Ge atoms. There are two shorter (3.03 Å) and two longer (3.07 Å) Dy–Rh bond lengths. There are a spread of Dy–Ge bond distances ranging from 3.01–3.31 Å. In the second Dy site, Dy is bonded in a 7-coordinate geometry to four equivalent Rh and five Ge atoms. There are a spread of Dy–Rh bond distances ranging from 2.91–3.15 Å. There are a spread of Dy–Ge bond distances ranging from 3.00–3.36 Å. Rh is bonded in a 9-coordinate geometry to six Dy and three Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.54–2.62 Å. 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 Rh atoms. In the second Ge site, Ge is bonded in a 12-coordinate geometry to eight Dy and four equivalent Rh atoms.
