The material described by Na3Yb is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Na(1) is bonded to eight equivalent Na(1) and four equivalent Yb(1) atoms to form NaNa8Yb4 cuboctahedra that share corners with twelve equivalent Na(1)Na8Yb4 cuboctahedra, edges with eight equivalent Yb(1)Na12 cuboctahedra, edges with sixteen equivalent Na(1)Na8Yb4 cuboctahedra, faces with four equivalent Yb(1)Na12 cuboctahedra, and faces with fourteen equivalent Na(1)Na8Yb4 cuboctahedra. Yb(1) is bonded to twelve equivalent Na(1) atoms to form YbNa12 cuboctahedra that share corners with twelve equivalent Yb(1)Na12 cuboctahedra, edges with twenty-four equivalent Na(1)Na8Yb4 cuboctahedra, faces with six equivalent Yb(1)Na12 cuboctahedra, and faces with twelve equivalent Na(1)Na8Yb4 cuboctahedra. is represented by the CIF file [CIF]
