Materials Data on Sc2MnSe4 by Materials Project
Sc2MnSe4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Sc3+ is bonded to six equivalent Se2- atoms to form ScSe6 octahedra that share corners with six equivalent MnSe4 tetrahedra and edges with six equivalent ScSe6 octahedra. All Sc–Se bond lengths are 2.72 Å. Mn2+ is bonded to four equivalent Se2- atoms to form MnSe4 tetrahedra that share corners with twelve equivalent ScSe6 octahedra. The corner-sharing octahedral tilt angles are 57°. All Mn–Se bond lengths are 2.53 Å. Se2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Sc3+ and one Mn2+ atom.
