Materials Data on Te2Ir by Materials Project
IrTe2 is Marcasite-like structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Ir4+ sites. In the first Ir4+ site, Ir4+ is bonded to six Te2- atoms to form a mixture of corner and edge-sharing IrTe6 octahedra. The corner-sharing octahedra tilt angles range from 56–60°. There are four shorter (2.68 Å) and two longer (2.70 Å) Ir–Te bond lengths. In the second Ir4+ site, Ir4+ is bonded to six Te2- atoms to form a mixture of corner and edge-sharing IrTe6 octahedra. The corner-sharing octahedra tilt angles range from 56–60°. There are a spread of Ir–Te bond distances ranging from 2.63–2.77 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 3-coordinate geometry to three Ir4+ atoms. In the second Te2- site, Te2- is bonded in a 3-coordinate geometry to three equivalent Ir4+ atoms. In the third Te2- site, Te2- is bonded in a 4-coordinate geometry to three Ir4+ and one Te2- atom. The Te–Te bond length is 2.99 Å.
