The structure described by BaY2F8 crystallizes in the tetragonal P4/mmm space group. Ba(1) is bonded in a distorted hexagonal bipyramidal geometry to eight equivalent F(1) atoms. Y(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. F(1) is bonded in a trigonal non-coplanar geometry to one Ba(1) and two equivalent Y(1) atoms. is represented by the CIF file [CIF]
