BaYF5 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent F(1), two equivalent F(3), and six equivalent F(2) atoms. Y(1) is bonded in a 8-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal non-coplanar geometry to one Ba(1) and two equivalent Y(1) atoms. In the second F site, F(2) is bonded to three equivalent Ba(1) and one Y(1) atom to form a mixture of corner and edge-sharing FBa3Y tetrahedra. In the third F site, F(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Ba(1) and two equivalent Y(1) atoms.
BaYF5 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent F(1), two equivalent F(3), and six equivalent F(2) atoms. Both Ba(1)-F(1) bond lengths are 2.69 Å. Both Ba(1)-F(3) bond lengths are 3.07 Å. There are two shorter (2.69 Å) and four longer (2.72 Å) Ba(1)-F(2) bond lengths. Y(1) is bonded in a 8-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. Both Y(1)-F(2) bond lengths are 2.26 Å. Both Y(1)-F(3) bond lengths are 2.32 Å. There are two shorter (2.24 Å) and two longer (2.30 Å) Y(1)-F(1) bond lengths. There are three inequivalent F sites.
