The Materials Project

Ir3Se8 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ir+3.33+ is bonded to six Se+1.25- atoms to form corner-sharing IrSe6 octahedra. The corner-sharing octahedra tilt angles range from 63–64°. There are a spread of Ir–Se bond distances ranging from 2.51–2.53 Å. There are two inequivalent Se+1.25- sites. In the first Se+1.25- site, Se+1.25- is bonded in a 2-coordinate geometry to two equivalent Ir+3.33+ and one Se+1.25- atom. The Se–Se bond length is 2.49 Å. In the second Se+1.25- site, Se+1.25- is bonded in a 3-coordinate geometry to three equivalent Ir+3.33+ and one Se+1.25- atom. The Se–Se bond length is 2.61 Å.
