ScF3 is alpha Rhenium trioxide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sc3+ is bonded to six equivalent F1- atoms to form corner-sharing ScF6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sc–F bond lengths are 2.03 Å. F1- is bonded in a linear geometry to two equivalent Sc3+ atoms.
ScF3 is alpha Rhenium trioxide structured and crystallizes in the trigonal R32 space group. The structure is three-dimensional. Sc3+ is bonded to six equivalent F1- atoms to form corner-sharing ScF6 octahedra. The corner-sharing octahedral tilt angles are 4°. All Sc–F bond lengths are 2.04 Å. F1- is bonded in a linear geometry to two equivalent Sc3+ atoms.
ScF3 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Sc3+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Sc–F bond distances ranging from 2.02–2.60 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Sc3+ atoms. In the second F1- site, F1- is bonded in a 4-coordinate geometry to four equivalent Sc3+ atoms.
ScF3 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Sc3+ is bonded to eight F1- atoms to form a mixture of distorted corner and edge-sharing ScF8 hexagonal bipyramids. There are a spread of Sc–F bond distances ranging from 2.08–2.51 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Sc3+ atoms. In the second F1- site, F1- is bonded in a distorted square co-planar geometry to four equivalent Sc3+ atoms.
