Na Na Ir Rh
Na2IrRh crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 12-coordinate geometry to two equivalent Na(1), four equivalent Na(2), four equivalent Ir(1), and two equivalent Rh(1) atoms. Both Na(1)-Na(1) bond lengths are 2.70 Å. There are a spread of Na(1)-Na(2) bond distances ranging from 2.41-3.21 Å. There are a spread of Na(1)-Ir(1) bond distances ranging from 2.71-3.46 Å. There is one shorter (2.61 Å) and one longer (2.81 Å) Na(1)-Rh(1) bond length. In the second Na site, Na(2) is bonded in a 2-coordinate geometry to four equivalent Na(1) and two equivalent Ir(1) atoms. There is one shorter (2.71 Å) and one longer (2.90 Å) Na(2)-Ir(1) bond length. Ir(1) is bonded in a 5-coordinate geometry to two equivalent Na(2), four equivalent Na(1), and one Rh(1) atom. The Ir(1)-Rh(1) bond length is 2.11 Å. Rh(1) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one Ir(1) atom.
