Title: Materials Data on Sm2GeRh3 by Materials Project

Abstract

Sm2Rh3Ge crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Sm is bonded in a 9-coordinate geometry to four equivalent Sm, nine equivalent Rh, and three equivalent Ge atoms. There are one shorter (3.10 Å) and three longer (3.40 Å) Sm–Sm bond lengths. There are three shorter (2.96 Å) and six longer (3.23 Å) Sm–Rh bond lengths. All Sm–Ge bond lengths are 3.31 Å. Rh is bonded to six equivalent Sm, four equivalent Rh, and two equivalent Ge atoms to form distorted RhSm6Ge2Rh4 cuboctahedra that share corners with four equivalent GeSm6Rh6 cuboctahedra, corners with fourteen equivalent RhSm6Ge2Rh4 cuboctahedra, edges with six equivalent RhSm6Ge2Rh4 cuboctahedra, faces with six equivalent GeSm6Rh6 cuboctahedra, and faces with twelve equivalent RhSm6Ge2Rh4 cuboctahedra. All Rh–Rh bond lengths are 2.84 Å. Both Rh–Ge bond lengths are 2.59 Å. Ge is bonded to six equivalent Sm and six equivalent Rh atoms to form distorted GeSm6Rh6 cuboctahedra that share corners with six equivalent GeSm6Rh6 cuboctahedra, corners with twelve equivalent RhSm6Ge2Rh4 cuboctahedra, edges with six equivalent GeSm6Rh6 cuboctahedra, and faces with eighteen equivalent RhSm6Ge2Rh4 cuboctahedra.
