Na3Ir is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 4-coordinate geometry to four equivalent Ir(1) atoms. In the second Na site, Na(2) is bonded in a distorted square co-planar geometry to four equivalent Ir(1) atoms. Ir(1) is bonded to four equivalent Na(2) and eight equivalent Na(1) atoms to form a mixture of corner, face, and edge-sharing IrNa12 cuboctahedra.
