AgInSe2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Ag(1) is bonded to four equivalent Se(1) atoms to form AgSe4 tetrahedra that share corners with four equivalent Ag(1)Se4 tetrahedra and corners with eight equivalent In(1)Se4 tetrahedra. In(1) is bonded to four equivalent Se(1) atoms to form InSe4 tetrahedra that share corners with four equivalent In(1)Se4 tetrahedra and corners with eight equivalent Ag(1)Se4 tetrahedra. Se(1) is bonded to two equivalent Ag(1) and two equivalent In(1) atoms to form corner-sharing SeIn2Ag2 tetrahedra.
AgInSe2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Ag(1) is bonded to four equivalent Se(1) atoms to form AgSe4 tetrahedra that share corners with four equivalent Ag(1)Se4 tetrahedra and corners with eight equivalent In(1)Se4 tetrahedra. All Ag(1)-Se(1) bond lengths are 2.65 Å. In(1) is bonded to four equivalent Se(1) atoms to form InSe4 tetrahedra that share corners with four equivalent In(1)Se4 tetrahedra and corners with eight equivalent Ag(1)Se4 tetrahedra. All In(1)-Se(1) bond lengths are 2.61 Å. Se(1) is bonded to two equivalent Ag(1) and two equivalent In(1) atoms to form corner-sharing SeIn2Ag2 tetrahedra.
