The crystal structure described by RuSe2 is Pyrite structured and crystallizes in the cubic Pa-3 space group. Ru(1) is bonded to six equivalent Se(1) atoms to form RuSe6 octahedra that share corners with twelve equivalent Ru(1)Se6 octahedra and corners with six equivalent Se(1)Ru3Se tetrahedra. The corner-sharing octahedral tilt angles are 64°. Se(1) is bonded to three equivalent Ru(1) and one Se(1) atom to form distorted SeRu3Se tetrahedra that share corners with three equivalent Ru(1)Se6 octahedra and corners with fifteen equivalent Se(1)Ru3Se tetrahedra. The corner-sharing octahedral tilt angles are 79°. is represented by the CIF file [CIF]
