Y(SO4)F crystallizes in the orthorhombic Pnma space group. Y(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), four equivalent O(3), and two equivalent F(1) atoms. S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Y(1) and one S(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Y(1) and one S(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Y(1) and one S(1) atom. F(1) is bonded in a linear geometry to two equivalent Y(1) atoms.
Y(SO4)F crystallizes in the orthorhombic Pnma space group. Y(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), four equivalent O(3), and two equivalent F(1) atoms. The Y(1)-O(1) bond length is 2.34 Å. The Y(1)-O(2) bond length is 2.35 Å. There are two shorter (2.33 Å) and two longer (2.60 Å) Y(1)-O(3) bond lengths. There is one shorter (2.21 Å) and one longer (2.23 Å) Y(1)-F(1) bond length. S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. The S(1)-O(1) bond length is 1.47 Å. The S(1)-O(2) bond length is 1.46 Å. Both S(1)-O(3) bond lengths are 1.51 Å. There are three inequivalent O sites.
