UCeCN is alpha Po-derived structured and crystallizes in the tetragonal P4/mmm space group. U(1) is bonded to four equivalent C(1) and two equivalent N(1) atoms to form UC4N2 octahedra that share corners with six equivalent U(1)C4N2 octahedra, edges with four equivalent U(1)C4N2 octahedra, and edges with eight equivalent Ce(1)C2N4 octahedra. The corner-sharing octahedra are not tilted. Ce(1) is bonded to two equivalent C(1) and four equivalent N(1) atoms to form CeC2N4 octahedra that share corners with six equivalent Ce(1)C2N4 octahedra, edges with four equivalent Ce(1)C2N4 octahedra, and edges with eight equivalent U(1)C4N2 octahedra. The corner-sharing octahedra are not tilted. C(1) is bonded to four equivalent U(1) and two equivalent Ce(1) atoms to form CCe2U4 octahedra that share corners with six equivalent C(1)Ce2U4 octahedra, edges with four equivalent C(1)Ce2U4 octahedra, and edges with eight equivalent N(1)Ce4U2 octahedra. The corner-sharing octahedra are not tilted. N(1) is bonded to two equivalent U(1) and four equivalent Ce(1) atoms to form NCe4U2 octahedra that share corners with six equivalent N(1)Ce4U2 octahedra, edges with four equivalent N(1)Ce4U2 octahedra, and edges with eight equivalent C(1)Ce2U4 octahedra. The corner-sharing octahedra are not tilted.
