AgSbSe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Ag(1) is bonded to six equivalent Se(1) atoms to form AgSe6 octahedra that share corners with six equivalent Sb(1)Se6 octahedra, edges with six equivalent Ag(1)Se6 octahedra, and edges with six equivalent Sb(1)Se6 octahedra. The corner-sharing octahedral tilt angles are 1°. Sb(1) is bonded to six equivalent Se(1) atoms to form SbSe6 octahedra that share corners with six equivalent Ag(1)Se6 octahedra, edges with six equivalent Ag(1)Se6 octahedra, and edges with six equivalent Sb(1)Se6 octahedra. The corner-sharing octahedral tilt angles are 1°. Se(1) is bonded to three equivalent Ag(1) and three equivalent Sb(1) atoms to form a mixture of corner and edge-sharing SeAg3Sb3 octahedra. The corner-sharing octahedra are not tilted.
