The compound described by UYSb2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. U(1) is bonded to six equivalent Sb(1) atoms to form USb6 octahedra that share corners with six equivalent Y(1)Sb6 octahedra, edges with six equivalent U(1)Sb6 octahedra, and edges with six equivalent Y(1)Sb6 octahedra. The corner-sharing octahedral tilt angles are 1°. Y(1) is bonded to six equivalent Sb(1) atoms to form YSb6 octahedra that share corners with six equivalent U(1)Sb6 octahedra, edges with six equivalent U(1)Sb6 octahedra, and edges with six equivalent Y(1)Sb6 octahedra. The corner-sharing octahedral tilt angles are 1°. Sb(1) is bonded to three equivalent U(1) and three equivalent Y(1) atoms to form a mixture of edge and corner-sharing SbY3U3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
