Sc2MnSe4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Sc(1) is bonded to six equivalent Se(1) atoms to form ScSe6 octahedra that share corners with six equivalent Mn(1)Se4 tetrahedra and edges with six equivalent Sc(1)Se6 octahedra. Mn(1) is bonded to four equivalent Se(1) atoms to form MnSe4 tetrahedra that share corners with twelve equivalent Sc(1)Se6 octahedra. The corner-sharing octahedral tilt angles are 57°. Se(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Sc(1) and one Mn(1) atom.
