Materials Data on Gd(GeRh)2 by Materials Project

Gd(RhGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Gd is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Ge atoms. All Gd–Rh bond lengths are 3.34 Å. All Gd–Ge bond lengths are 3.21 Å. Rh is bonded to four equivalent Gd and four equivalent Ge atoms to form a mixture of distorted edge, face, and corner-sharing RhGd4Ge4 tetrahedra. All Rh–Ge bond lengths are 2.47 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Gd, four equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.56 Å.

Materials Data on Gd(Ge2Rh3)2 by Materials Project

Gd(Rh3Ge2)2 crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Gd is bonded to six equivalent Rh and six equivalent Ge atoms to form face-sharing GdGe6Rh6 cuboctahedra. All Gd–Rh bond lengths are 3.16 Å. All Gd–Ge bond lengths are 3.13 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 5-coordinate geometry to five Ge atoms. There are one shorter (2.50 Å) and four longer (2.57 Å) Rh–Ge bond lengths. In the second Rh site, Rh is bonded in a 6-coordinate geometry to two equivalent Gd and four Ge atoms. There are two shorter (2.48 Å) and two longer (2.56 Å) Rh–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to nine Rh atoms. In the second Ge site, Ge is bonded in a 8-coordinate geometry to two equivalent Gd and six Rh atoms.
