YbF3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. Yb(1) is bonded to four equivalent F(2) and eight equivalent F(1) atoms to form a mixture of edge, corner, and face-sharing YbF12 cuboctahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded to four equivalent Yb(1) atoms to form a mixture of edge and corner-sharing FYb4 tetrahedra. In the second F site, F(2) is bonded in a square co-planar geometry to four equivalent Yb(1) atoms.
