Materials Data on SiIr3 by Materials Project
Ir3Si crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a distorted square co-planar geometry to four equivalent Si atoms. All Ir–Si bond lengths are 2.64 Å. In the second Ir site, Ir is bonded in a distorted water-like geometry to two equivalent Si atoms. Both Ir–Si bond lengths are 2.44 Å. Si is bonded in a 8-coordinate geometry to eight Ir atoms.
