Materials Data on In2SbAs by Materials Project
In2SbAs is Enargite-like structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to three equivalent Sb3- and one As3- atom to form corner-sharing InSb3As tetrahedra. All In–Sb bond lengths are 2.82 Å. The In–As bond length is 2.67 Å. In the second In3+ site, In3+ is bonded to one Sb3- and three equivalent As3- atoms to form corner-sharing InSbAs3 tetrahedra. The In–Sb bond length is 2.88 Å. All In–As bond lengths are 2.74 Å. Sb3- is bonded to four In3+ atoms to form SbIn4 tetrahedra that share corners with six equivalent SbIn4 tetrahedra and corners with six equivalent AsIn4 tetrahedra. As3- is bonded to four In3+ atoms to form AsIn4 tetrahedra that share corners with six equivalent SbIn4 tetrahedra and corners with six equivalent AsIn4 tetrahedra.
