The structure described by UC2 is Pyrite structured and crystallizes in the cubic Pa-3 space group. U(1) is bonded to six equivalent C(1) atoms to form UC6 octahedra that share corners with twelve equivalent U(1)C6 octahedra and corners with six equivalent C(1)U3C tetrahedra. The corner-sharing octahedral tilt angles are 72°. C(1) is bonded to three equivalent U(1) and one C(1) atom to form CU3C tetrahedra that share corners with three equivalent U(1)C6 octahedra and corners with fifteen equivalent C(1)U3C tetrahedra. The corner-sharing octahedral tilt angles are 69°. is represented by the CIF card [CIF]
