K Na Na Ru
KNa2Ru crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KNa2Ru cluster. K(1) is bonded in a 2-coordinate geometry to one Na(1) and one Ru(1) atom. The K(1)-Na(1) bond length is 1.88 Å. The K(1)-Ru(1) bond length is 2.58 Å. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 2-coordinate geometry to one K(1) and one Ru(1) atom. The Na(1)-Ru(1) bond length is 2.80 Å. In the second Na site, Na(2) is bonded in a distorted single-bond geometry to one Ru(1) atom. The Na(2)-Ru(1) bond length is 2.80 Å. Ru(1) is bonded in a 3-coordinate geometry to one K(1), one Na(1), and one Na(2) atom.
