Na Na Y Zn
Na2YZn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Na2YZn cluster. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 1-coordinate geometry to one Zn(1) atom. The Na(1)-Zn(1) bond length is 1.66 Å. In the second Na site, Na(2) is bonded in a distorted single-bond geometry to one Zn(1) atom. The Na(2)-Zn(1) bond length is 2.07 Å. Y(1) is bonded in a single-bond geometry to one Zn(1) atom. The Y(1)-Zn(1) bond length is 0.55 Å. Zn(1) is bonded in a distorted single-bond geometry to one Na(1), one Na(2), and one Y(1) atom.
