Materials Data on Na3Sc by Materials Project

Abstract

Na3Sc is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Na is bonded to eight equivalent Na and four equivalent Sc atoms to form distorted NaNa8Sc4 cuboctahedra that share corners with twelve equivalent NaNa8Sc4 cuboctahedra, edges with eight equivalent ScNa12 cuboctahedra, edges with sixteen equivalent NaNa8Sc4 cuboctahedra, faces with four equivalent ScNa12 cuboctahedra, and faces with fourteen equivalent NaNa8Sc4 cuboctahedra. All Na–Na bond lengths are 3.56 Å. All Na–Sc bond lengths are 3.56 Å. Sc is bonded to twelve equivalent Na atoms to form ScNa12 cuboctahedra that share corners with twelve equivalent ScNa12 cuboctahedra, edges with twenty-four equivalent NaNa8Sc4 cuboctahedra, faces with six equivalent ScNa12 cuboctahedra, and faces with twelve equivalent NaNa8Sc4 cuboctahedra.
