MnYb2Se4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Yb(1) is bonded to six equivalent Se(1) atoms to form YbSe6 octahedra that share corners with six equivalent Mn(1)Se4 tetrahedra and edges with six equivalent Yb(1)Se6 octahedra. Mn(1) is bonded to four equivalent Se(1) atoms to form MnSe4 tetrahedra that share corners with twelve equivalent Yb(1)Se6 octahedra. The corner-sharing octahedral tilt angles are 53°. Se(1) is bonded in a rectangular see-saw-like geometry to three equivalent Yb(1) and one Mn(1) atom.
