Materials Data on ScOF by Materials Project

ScOF is Baddeleyite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sc3+ is bonded to four equivalent O2- and three equivalent F1- atoms to form a mixture of distorted corner and edge-sharing ScO4F3 pentagonal bipyramids. There are a spread of Sc–O bond distances ranging from 2.08–2.16 Å. There are a spread of Sc–F bond distances ranging from 2.15–2.30 Å. O2- is bonded to four equivalent Sc3+ atoms to form a mixture of distorted corner and edge-sharing OSc4 tetrahedra. F1- is bonded in a 3-coordinate geometry to three equivalent Sc3+ atoms.

Materials Data on ScOF by Materials Project

ScOF is zeta iron carbide-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sc3+ is bonded to three equivalent O2- and three equivalent F1- atoms to form a mixture of distorted edge and corner-sharing ScO3F3 octahedra. The corner-sharing octahedra tilt angles range from 45–60°. There are a spread of Sc–O bond distances ranging from 1.98–2.04 Å. There are two shorter (2.19 Å) and one longer (2.33 Å) Sc–F bond lengths. O2- is bonded in a distorted trigonal planar geometry to three equivalent Sc3+ atoms. F1- is bonded in a distorted trigonal planar geometry to three equivalent Sc3+ atoms.

Materials Data on ScOF by Materials Project

ScOF crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sc3+ is bonded in a body-centered cubic geometry to four equivalent O2- and four equivalent F1- atoms. All Sc–O bond lengths are 2.10 Å. All Sc–F bond lengths are 2.37 Å. O2- is bonded to four equivalent Sc3+ atoms to form distorted OSc4 tetrahedra that share corners with four equivalent OSc4 tetrahedra, corners with twelve equivalent FSc4 tetrahedra, edges with two equivalent FSc4 tetrahedra, and edges with four equivalent OSc4 tetrahedra. F1- is bonded to four equivalent Sc3+ atoms to form distorted FSc4 tetrahedra that share corners with four equivalent FSc4 tetrahedra, corners with twelve equivalent OSc4 tetrahedra, edges with two equivalent OSc4 tetrahedra, and edges with four equivalent FSc4 tetrahedra.
