The material described by YSeF crystallizes in the orthorhombic Pnma space group. Y(1) is bonded to four equivalent Se(1) and three equivalent F(1) atoms to form a mixture of distorted corner and edge-sharing YSe4F3 pentagonal bipyramids. Se(1) is bonded in a rectangular see-saw-like geometry to four equivalent Y(1) atoms. F(1) is bonded in a trigonal planar geometry to three equivalent Y(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
