The material structure described by Ag3In4(GeSe4)4 crystallizes in the tetragonal I-4 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to two equivalent Se(1) and two equivalent Se(2) atoms to form AgSe4 tetrahedra that share corners with two equivalent Ge(1)Se4 tetrahedra, corners with two equivalent Ge(2)Se4 tetrahedra, and corners with four equivalent In(1)Se4 tetrahedra. In the second Ag site, Ag(2) is bonded to four equivalent Se(4) atoms to form AgSe4 tetrahedra that share corners with four equivalent In(1)Se4 tetrahedra and corners with four equivalent Ge(3)Se4 tetrahedra. In(1) is bonded to one Se(1), one Se(2), one Se(3), and one Se(4) atom to form InSe4 tetrahedra that share  a cornercorner with one Ag(2)Se4 tetrahedra,  a cornercorner with one Ge(1)Se4 tetrahedra,  a cornercorner with one Ge(2)Se4 tetrahedra, corners with two equivalent Ag(1)Se4 tetrahedra, and corners with two equivalent Ge(3)Se4 tetrahedra. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent Se(2) atoms to form GeSe4 tetrahedra that share corners with four equivalent Ag(1)Se4 tetrahedra and corners with four equivalent In(1)Se4 tetrahedra. In the second Ge site, Ge(2) is bonded to four equivalent Se(1) atoms to form GeSe4 tetrahedra that share corners with four equivalent Ag(1)Se4 tetrahedra and corners with four equivalent In(1)Se4 tetrahedra. In the third Ge site, Ge(3) is bonded to two equivalent Se(3) and two equivalent Se(4) atoms to form GeSe4 tetrahedra that share corners with two equivalent Ag(2)Se4 tetrahedra and corners with four equivalent In(1)Se4 tetrahedra. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded in a trigonal non-coplanar geometry to one Ag(1), one In(1), and one Ge(2) atom. In the second Se site, Se(2) is bonded in a trigonal non-coplanar geometry to one Ag(1), one In(1), and one Ge(1) atom. In the third Se site, Se(3) is bonded in a water-like geometry to one In(1) and one Ge(3) atom. In the fourth Se site, Se(4) is bonded in a trigonal non-coplanar geometry to one Ag(2), one In(1), and one Ge(3) atom. is represented by the CIF card [CIF]
