Materials Data on SmIn3 by Materials Project

Abstract

SmIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sm is bonded to twelve equivalent In atoms to form SmIn12 cuboctahedra that share corners with twelve equivalent SmIn12 cuboctahedra, edges with twenty-four equivalent InSm4In8 cuboctahedra, faces with six equivalent SmIn12 cuboctahedra, and faces with twelve equivalent InSm4In8 cuboctahedra. All Sm–In bond lengths are 3.31 Å. In is bonded to four equivalent Sm and eight equivalent In atoms to form distorted InSm4In8 cuboctahedra that share corners with twelve equivalent InSm4In8 cuboctahedra, edges with eight equivalent SmIn12 cuboctahedra, edges with sixteen equivalent InSm4In8 cuboctahedra, faces with four equivalent SmIn12 cuboctahedra, and faces with fourteen equivalent InSm4In8 cuboctahedra. All In–In bond lengths are 3.31 Å.
