The structure described by Yb3Os is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to four equivalent Yb(2) and four equivalent Os(1) atoms to form distorted YbYb4Os4 tetrahedra that share corners with eight equivalent Yb(2)Yb8Os4 cuboctahedra, corners with eight equivalent Os(1)Yb12 cuboctahedra, corners with eight equivalent Yb(1)Yb4Os4 tetrahedra, edges with four equivalent Yb(2)Yb8Os4 cuboctahedra, edges with four equivalent Os(1)Yb12 cuboctahedra, edges with twelve equivalent Yb(1)Yb4Os4 tetrahedra, and faces with six equivalent Yb(1)Yb4Os4 tetrahedra. In the second Yb site, Yb(2) is bonded to eight equivalent Yb(1) and four equivalent Os(1) atoms to form distorted YbYb8Os4 cuboctahedra that share corners with four equivalent Yb(2)Yb8Os4 cuboctahedra, corners with eight equivalent Os(1)Yb12 cuboctahedra, corners with sixteen equivalent Yb(1)Yb4Os4 tetrahedra, edges with eight equivalent Yb(2)Yb8Os4 cuboctahedra, edges with eight equivalent Yb(1)Yb4Os4 tetrahedra, faces with four equivalent Yb(2)Yb8Os4 cuboctahedra, and faces with six equivalent Os(1)Yb12 cuboctahedra.
