YSeF crystallizes in the orthorhombic Pnma space group. Y(1) is bonded in a 2-coordinate geometry to five equivalent Se(1) and two equivalent F(1) atoms. Se(1) is bonded to five equivalent Y(1) atoms to form a mixture of corner and edge-sharing SeY5 trigonal bipyramids. F(1) is bonded in a bent 150 degrees geometry to two equivalent Y(1) atoms.
YSeF crystallizes in the orthorhombic Pnma space group. Y(1) is bonded in a 2-coordinate geometry to five equivalent Se(1) and two equivalent F(1) atoms. There are a spread of Y(1)-Se(1) bond distances ranging from 2.87-3.17 Å. There is one shorter (2.17 Å) and one longer (2.18 Å) Y(1)-F(1) bond length. Se(1) is bonded to five equivalent Y(1) atoms to form a mixture of corner and edge-sharing SeY5 trigonal bipyramids. F(1) is bonded in a bent 150 degrees geometry to two equivalent Y(1) atoms.
