Ho3(AgSn)4 crystallizes in the orthorhombic Immm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 12-coordinate geometry to six equivalent Ag(1), two equivalent Sn(2), and four equivalent Sn(1) atoms. In the second Ho site, Ho(2) is bonded to eight equivalent Ag(1), two equivalent Sn(2), and four equivalent Sn(1) atoms to form distorted face-sharing HoAg8Sn6 octahedra. Ag(1) is bonded in a 12-coordinate geometry to two equivalent Ho(2), three equivalent Ho(1), three equivalent Ag(1), one Sn(1), and three equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to two equivalent Ho(2), four equivalent Ho(1), two equivalent Ag(1), and one Sn(1) atom. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to one Ho(2), two equivalent Ho(1), and six equivalent Ag(1) atoms.
