Abstract

MgEu2Se4 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 EuSe6 octahedra. The corner-sharing octahedral tilt angles are 56°. All Mg–Se bond lengths are 2.64 Å. Eu3+ is bonded to six equivalent Se2- atoms to form EuSe6 octahedra that share corners with six equivalent MgSe4 tetrahedra and edges with six equivalent EuSe6 octahedra. All Eu–Se bond lengths are 2.96 Å. Se2- is bonded in a distorted rectangular see-saw-like geometry to one Mg2+ and three equivalent Eu3+ atoms.
