The structure described by AgHoSe2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Ho(1) is bonded to two equivalent Se(2) and four equivalent Se(1) atoms to form HoSe6 octahedra that share corners with six equivalent Ho(1)Se6 octahedra, edges with four equivalent Ho(1)Se6 octahedra, and edges with eight equivalent Ag(1)Se6 octahedra. The corner-sharing octahedra are not tilted. Ag(1) is bonded to two equivalent Se(1) and four equivalent Se(2) atoms to form AgSe6 octahedra that share corners with six equivalent Ag(1)Se6 octahedra, edges with four equivalent Ag(1)Se6 octahedra, and edges with eight equivalent Ho(1)Se6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded to four equivalent Ho(1) and two equivalent Ag(1) atoms to form SeHo4Ag2 octahedra that share corners with six equivalent Se(1)Ho4Ag2 octahedra, edges with four equivalent Se(1)Ho4Ag2 octahedra, and edges with eight equivalent Se(2)Ho2Ag4 octahedra. The corner-sharing octahedra are not tilted. In the second Se site, Se(2) is bonded to two equivalent Ho(1) and four equivalent Ag(1) atoms to form SeHo2Ag4 octahedra that share corners with six equivalent Se(2)Ho2Ag4 octahedra, edges with four equivalent Se(2)Ho2Ag4 octahedra, and edges with eight equivalent Se(1)Ho4Ag2 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
