Materials Data on InSb by Materials Project
InSb is High Pressure Cadmuum Telluride structured and crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. In3+ is bonded in a bent 150 degrees geometry to two equivalent Sb3- atoms. Both In–Sb bond lengths are 3.18 Å. Sb3- is bonded to two equivalent In3+ and four equivalent Sb3- atoms to form a mixture of edge and corner-sharing SbIn2Sb4 octahedra. The corner-sharing octahedra tilt angles range from 0–29°. There are two shorter (3.04 Å) and two longer (3.14 Å) Sb–Sb bond lengths.
