Materials Data on Te8Ir3 by Materials Project
Ir3Te8 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ir+3.33+ is bonded to six Te+1.25- atoms to form corner-sharing IrTe6 octahedra. The corner-sharing octahedra tilt angles range from 62–64°. There are two shorter (2.68 Å) and four longer (2.71 Å) Ir–Te bond lengths. There are two inequivalent Te+1.25- sites. In the first Te+1.25- site, Te+1.25- is bonded in a 2-coordinate geometry to two equivalent Ir+3.33+ atoms. In the second Te+1.25- site, Te+1.25- is bonded in a 4-coordinate geometry to three equivalent Ir+3.33+ and one Te+1.25- atom. The Te–Te bond length is 2.93 Å.
