KNa5 crystallizes in the triclinic P1 space group. K(1) is bonded in a single-bond geometry to one Na(1), one Na(2), one Na(4), and one Na(5) atom. The K(1)-Na(1) bond length is 2.82 Å. The K(1)-Na(2) bond length is 2.88 Å. The K(1)-Na(4) bond length is 2.10 Å. The K(1)-Na(5) bond length is 1.37 Å. There are five inequivalent Na sites. In the first Na site, Na(1) is bonded in a 5-coordinate geometry to one K(1), one Na(4), one Na(5), and two equivalent Na(1) atoms. The Na(1)-Na(4) bond length is 3.65 Å. The Na(1)-Na(5) bond length is 2.53 Å. Both Na(1)-Na(1) bond lengths are 3.86 Å. In the second Na site, Na(2) is bonded in a distorted bent 120 degrees geometry to one K(1) and one Na(3) atom. The Na(2)-Na(3) bond length is 2.62 Å. In the third Na site, Na(3) is bonded in a 4-coordinate geometry to one Na(2), one Na(4), and two equivalent Na(3) atoms. The Na(3)-Na(4) bond length is 3.42 Å. Both Na(3)-Na(3) bond lengths are 3.86 Å. In the fourth Na site, Na(4) is bonded in a 2-coordinate geometry to one K(1), one Na(1), one Na(3), and one Na(5) atom. The Na(4)-Na(5) bond length is 1.70 Å. In the fifth Na site, Na(5) is bonded in a distorted single-bond geometry to one K(1), one Na(1), and one Na(4) atom.
