Materials Data on InGaSb2 by Materials Project
InGaSb2 is Chalcopyrite-like structured and crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. In3+ is bonded to four equivalent Sb3- atoms to form InSb4 tetrahedra that share corners with four equivalent InSb4 tetrahedra and corners with eight equivalent GaSb4 tetrahedra. All In–Sb bond lengths are 2.85 Å. Ga3+ is bonded to four equivalent Sb3- atoms to form GaSb4 tetrahedra that share corners with four equivalent GaSb4 tetrahedra and corners with eight equivalent InSb4 tetrahedra. All Ga–Sb bond lengths are 2.73 Å. Sb3- is bonded to two equivalent In3+ and two equivalent Ga3+ atoms to form corner-sharing SbIn2Ga2 tetrahedra.
