Materials Data on GaSb by Materials Project

Abstract

GaSb crystallizes in the triclinic P1 space group. The structure is three-dimensional. Ga3+ is bonded to six equivalent Sb3- atoms to form distorted GaSb6 octahedra that share corners with twelve equivalent SbGa6Sb2 hexagonal bipyramids, corners with six equivalent GaSb6 octahedra, and edges with twelve equivalent GaSb6 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. There are a spread of Ga–Sb bond distances ranging from 2.89–3.11 Å. Sb3- is bonded to six equivalent Ga3+ and two equivalent Sb3- atoms to form distorted SbGa6Sb2 hexagonal bipyramids that share corners with eight equivalent SbGa6Sb2 hexagonal bipyramids, corners with twelve equivalent GaSb6 octahedra, and edges with twelve equivalent SbGa6Sb2 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 59–121°. Both Sb–Sb bond lengths are 3.11 Å.
