AgInGeSe4 crystallizes in the tetragonal I-4 space group. Ag(1) is bonded to four equivalent Se(1) atoms to form AgSe4 tetrahedra that share corners with four equivalent In(1)Se4 tetrahedra and corners with four equivalent Ge(1)Se4 tetrahedra. In(1) is bonded to four equivalent Se(1) atoms to form InSe4 tetrahedra that share corners with four equivalent Ag(1)Se4 tetrahedra and corners with four equivalent Ge(1)Se4 tetrahedra. Ge(1) 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. Se(1) is bonded in a trigonal non-coplanar geometry to one Ag(1), one In(1), and one Ge(1) atom.
