Na Ir Ru Ru
NaRu2Ir crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaRu2Ir clusters. Na(1) is bonded in a 2-coordinate geometry to two equivalent Ru(1) and one Ir(1) atom. Both Na(1)-Ru(1) bond lengths are 1.89 Å. The Na(1)-Ir(1) bond length is 2.22 Å. Ru(1) is bonded in a 1-coordinate geometry to one Na(1) and one Ir(1) atom. The Ru(1)-Ir(1) bond length is 1.89 Å. Ir(1) is bonded in a 3-coordinate geometry to one Na(1) and two equivalent Ru(1) atoms.
