AgIn2Se3Cl is Spinel-derived structured and crystallizes in the trigonal R-3m space group. Ag(1) is bonded to three equivalent Se(1) and one Cl(1) atom to form AgSe3Cl trigonal pyramids that share corners with three equivalent In(1)Se6 octahedra and corners with nine equivalent In(2)Se4Cl2 octahedra. The corner-sharing octahedral tilt angles range from 49-63°. There are two inequivalent In sites. In the first In site, In(1) is bonded to six equivalent Se(1) atoms to form InSe6 octahedra that share corners with six equivalent Ag(1)Se3Cl trigonal pyramids and edges with six equivalent In(2)Se4Cl2 octahedra. In the second In site, In(2) is bonded to four equivalent Se(1) and two equivalent Cl(1) atoms to form InSe4Cl2 octahedra that share corners with six equivalent Ag(1)Se3Cl trigonal pyramids, edges with two equivalent In(1)Se6 octahedra, and edges with four equivalent In(2)Se4Cl2 octahedra. Se(1) is bonded in a rectangular see-saw-like geometry to one Ag(1), one In(1), and two equivalent In(2) atoms. Cl(1) is bonded in a rectangular see-saw-like geometry to one Ag(1) and three equivalent In(2) atoms.
