NaZn5 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaZn5 cluster. Na(1) is bonded in a distorted linear geometry to one Zn(2) and one Zn(3) atom. The Na(1)-Zn(2) bond length is 1.01 Å. The Na(1)-Zn(3) bond length is 1.87 Å. There are five inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a single-bond geometry to one Zn(4) atom. The Zn(1)-Zn(4) bond length is 0.75 Å. In the second Zn site, Zn(2) is bonded in a single-bond geometry to one Na(1) and one Zn(4) atom. The Zn(2)-Zn(4) bond length is 1.67 Å. In the third Zn site, Zn(3) is bonded in a distorted linear geometry to one Na(1) and one Zn(5) atom. The Zn(3)-Zn(5) bond length is 1.23 Å. In the fourth Zn site, Zn(4) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one Zn(2) atom. In the fifth Zn site, Zn(5) is bonded in a single-bond geometry to one Zn(3) atom.
