Materials Data on LaGe2Rh by Materials Project

Abstract

LaRhGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. La is bonded in a 4-coordinate geometry to four equivalent Rh and ten Ge atoms. All La–Rh bond lengths are 3.36 Å. There are a spread of La–Ge bond distances ranging from 3.31–3.41 Å. Rh is bonded in a 5-coordinate geometry to four equivalent La and five Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.43–2.51 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent La, one Rh, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.63 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent La and four equivalent Rh atoms.
