The material described by Co3Se is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Co(1) is bonded to eight equivalent Co(1) and four equivalent Se(1) atoms to form distorted CoCo8Se4 cuboctahedra that share corners with twelve equivalent Co(1)Co8Se4 cuboctahedra, edges with eight equivalent Se(1)Co12 cuboctahedra, edges with sixteen equivalent Co(1)Co8Se4 cuboctahedra, faces with four equivalent Se(1)Co12 cuboctahedra, and faces with fourteen equivalent Co(1)Co8Se4 cuboctahedra. Se(1) is bonded to twelve equivalent Co(1) atoms to form SeCo12 cuboctahedra that share corners with twelve equivalent Se(1)Co12 cuboctahedra, edges with twenty-four equivalent Co(1)Co8Se4 cuboctahedra, faces with six equivalent Se(1)Co12 cuboctahedra, and faces with twelve equivalent Co(1)Co8Se4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
