Title: Materials Data on Tm2MgSe4 by Materials Project

Abstract

MgTm2Se4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Mg2+ is bonded to four equivalent Se2- atoms to form MgSe4 tetrahedra that share corners with twelve equivalent TmSe6 octahedra. The corner-sharing octahedral tilt angles are 57°. All Mg–Se bond lengths are 2.62 Å. Tm3+ is bonded to six equivalent Se2- atoms to form TmSe6 octahedra that share corners with six equivalent MgSe4 tetrahedra and edges with six equivalent TmSe6 octahedra. All Tm–Se bond lengths are 2.83 Å. Se2- is bonded in a distorted rectangular see-saw-like geometry to one Mg2+ and three equivalent Tm3+ atoms.
