Y2(OF)3 crystallizes in the hexagonal P-6 space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted q6 geometry to three equivalent O(1) and six equivalent F(1) atoms. In the second Y site, Y(2) is bonded in a 9-coordinate geometry to six equivalent O(1) and three equivalent F(1) atoms. O(1) is bonded in a trigonal non-coplanar geometry to one Y(1) and two equivalent Y(2) atoms. F(1) is bonded in a trigonal non-coplanar geometry to one Y(2) and two equivalent Y(1) atoms.
Y2(OF)3 crystallizes in the hexagonal P-6 space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted q6 geometry to three equivalent O(1) and six equivalent F(1) atoms. All Y(1)-O(1) bond lengths are 2.37 Å. All Y(1)-F(1) bond lengths are 2.44 Å. In the second Y site, Y(2) is bonded in a 9-coordinate geometry to six equivalent O(1) and three equivalent F(1) atoms. All Y(2)-O(1) bond lengths are 2.34 Å. All Y(2)-F(1) bond lengths are 2.32 Å.
