The crystal structure described by RhSe2 is Pyrite structured and crystallizes in the cubic Pa-3 space group. Rh(1) is bonded to six equivalent Se(1) atoms to form RhSe6 octahedra that share corners with twelve equivalent Rh(1)Se6 octahedra and corners with six equivalent Se(1)Rh3Se tetrahedra. The corner-sharing octahedral tilt angles are 63°. Se(1) is bonded to three equivalent Rh(1) and one Se(1) atom to form distorted SeRh3Se tetrahedra that share corners with three equivalent Rh(1)Se6 octahedra and corners with fifteen equivalent Se(1)Rh3Se tetrahedra. The corner-sharing octahedral tilt angles are 79°. is represented by the Crystallographic Information File (CIF) [CIF]
