MnSe2 is pyrite-like structured and crystallizes in the cubic Pa-3 space group. Mn(1) is bonded to six equivalent Se(1) atoms to form corner-sharing MnSe6 octahedra. The corner-sharing octahedral tilt angles are 62°. Se(1) is bonded in a distorted trigonal planar geometry to three equivalent Mn(1) atoms.
