Materials Data on LaIn5Rh by Materials Project

Abstract

LaRhIn5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. La is bonded to twelve In atoms to form LaIn12 cuboctahedra that share corners with four equivalent LaIn12 cuboctahedra, faces with four equivalent LaIn12 cuboctahedra, and faces with four equivalent InLa4In8 cuboctahedra. All La–In bond lengths are 3.35 Å. Rh is bonded in a body-centered cubic geometry to eight equivalent In atoms. All Rh–In bond lengths are 2.80 Å. There are two inequivalent In sites. In the first In site, In is bonded to four equivalent La and eight equivalent In atoms to form distorted InLa4In8 cuboctahedra that share corners with four equivalent InLa4In8 cuboctahedra, faces with four equivalent LaIn12 cuboctahedra, and faces with four equivalent InLa4In8 cuboctahedra. All In–In bond lengths are 3.35 Å. In the second In site, In is bonded in a 2-coordinate geometry to two equivalent La, two equivalent Rh, and two equivalent In atoms.
