Materials Data on Sc2(SO4)3 by Materials Project

Sc2(SO4)3 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share corners with six equivalent SO4 tetrahedra. There are three shorter (2.09 Å) and three longer (2.10 Å) Sc–O bond lengths. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent ScO6 octahedra. The corner-sharing octahedra tilt angles range from 24–27°. All S–O bond lengths are 1.48 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Sc3+ and one S6+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Sc3+ and one S6+ atom.

Materials Data on Sc2SO2 by Materials Project

Sc2SO2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sc3+ is bonded in a 4-coordinate geometry to three equivalent S2- and four equivalent O2- atoms. All Sc–S bond lengths are 2.73 Å. There are three shorter (2.11 Å) and one longer (2.18 Å) Sc–O bond lengths. S2- is bonded in a 6-coordinate geometry to six equivalent Sc3+ atoms. O2- is bonded to four equivalent Sc3+ atoms to form a mixture of edge and corner-sharing OSc4 tetrahedra.
