Materials Data on YUSb2 by Materials Project
UYSb2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. U3+ is bonded to six equivalent Sb3- atoms to form USb6 octahedra that share corners with six equivalent YSb6 octahedra, edges with six equivalent USb6 octahedra, and edges with six equivalent YSb6 octahedra. The corner-sharing octahedral tilt angles are 0°. All U–Sb bond lengths are 3.11 Å. Y3+ is bonded to six equivalent Sb3- atoms to form YSb6 octahedra that share corners with six equivalent USb6 octahedra, edges with six equivalent USb6 octahedra, and edges with six equivalent YSb6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Y–Sb bond lengths are 3.10 Å. Sb3- is bonded to three equivalent U3+ and three equivalent Y3+ atoms to form a mixture of edge and corner-sharing SbY3U3 octahedra. The corner-sharing octahedral tilt angles are 0°.
