AgHoSe2 crystallizes in the orthorhombic P2_12_12_1 space group. Ho(1) is bonded to three equivalent Se(1) and three equivalent Se(2) atoms to form a mixture of edge and corner-sharing HoSe6 octahedra. The corner-sharing octahedral tilt angles range from 43-51°. Ag(1) is bonded in a 4-coordinate geometry to two equivalent Se(1) and two equivalent Se(2) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded to three equivalent Ho(1) and two equivalent Ag(1) atoms to form a mixture of distorted edge and corner-sharing SeHo3Ag2 trigonal bipyramids. In the second Se site, Se(2) is bonded to three equivalent Ho(1) and two equivalent Ag(1) atoms to form a mixture of distorted edge and corner-sharing SeHo3Ag2 trigonal bipyramids.
AgHoSe2 crystallizes in the orthorhombic P2_12_12_1 space group. Ho(1) is bonded to three equivalent Se(1) and three equivalent Se(2) atoms to form a mixture of edge and corner-sharing HoSe6 octahedra. The corner-sharing octahedral tilt angles range from 43-51°. There are a spread of Ho(1)-Se(1) bond distances ranging from 2.84-2.87 Å. There are a spread of Ho(1)-Se(2) bond distances ranging from 2.84-2.87 Å. Ag(1) is bonded in a 4-coordinate geometry to two equivalent Se(1) and two equivalent Se(2) atoms. Both Ag(1)-Se(1) bond lengths are 2.73 Å. There is one shorter (2.70 Å) and one longer (2.71 Å) Ag(1)-Se(2) bond length. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded to three equivalent Ho(1) and two equivalent Ag(1) atoms to form a mixture of distorted edge and corner-sharing SeHo3Ag2 trigonal bipyramids. In the second Se site, Se(2) is bonded to three equivalent Ho(1) and two equivalent Ag(1) atoms to form a mixture of distorted edge and corner-sharing SeHo3Ag2 trigonal bipyramids.
