Materials Data on YbF2 by Materials Project
YbF2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Yb2+ is bonded to six equivalent F1- atoms to form a mixture of edge and corner-sharing YbF6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are two shorter (2.23 Å) and four longer (2.25 Å) Yb–F bond lengths. F1- is bonded in a trigonal planar geometry to three equivalent Yb2+ atoms.
