RbMnSe2 crystallizes in the tetragonal I-4m2 space group. Rb(1) is bonded in a body-centered cubic geometry to eight equivalent Se(1) atoms. Mn(1) is bonded to four equivalent Se(1) atoms to form corner-sharing MnSe4 tetrahedra. Se(1) is bonded in a distorted water-like geometry to four equivalent Rb(1) and two equivalent Mn(1) atoms.
