Materials Data on Na3Yb by Materials Project

Abstract

Na3Yb 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 Yb atoms to form NaNa8Yb4 cuboctahedra that share corners with twelve equivalent NaNa8Yb4 cuboctahedra, edges with eight equivalent YbNa12 cuboctahedra, edges with sixteen equivalent NaNa8Yb4 cuboctahedra, faces with four equivalent YbNa12 cuboctahedra, and faces with fourteen equivalent NaNa8Yb4 cuboctahedra. All Na–Na bond lengths are 3.80 Å. All Na–Yb bond lengths are 3.80 Å. Yb is bonded to twelve equivalent Na atoms to form YbNa12 cuboctahedra that share corners with twelve equivalent YbNa12 cuboctahedra, edges with twenty-four equivalent NaNa8Yb4 cuboctahedra, faces with six equivalent YbNa12 cuboctahedra, and faces with twelve equivalent NaNa8Yb4 cuboctahedra.
