Materials Data on InAgSe2 by Materials Project
Abstract
AgInSe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Ag1+ is bonded to six equivalent Se2- atoms to form AgSe6 octahedra that share corners with six equivalent InSe6 octahedra, edges with six equivalent AgSe6 octahedra, and edges with six equivalent InSe6 octahedra. The corner-sharing octahedral tilt angles are 2°. All Ag–Se bond lengths are 2.88 Å. In3+ is bonded to six equivalent Se2- atoms to form InSe6 octahedra that share corners with six equivalent AgSe6 octahedra, edges with six equivalent AgSe6 octahedra, and edges with six equivalent InSe6 octahedra. The corner-sharing octahedral tilt angles are 2°. All In–Se bond lengths are 2.82 Å. Se2- is bonded to three equivalent Ag1+ and three equivalent In3+ atoms to form a mixture of corner and edge-sharing SeIn3Ag3 octahedra. The corner-sharing octahedral tilt angles are 0°.
