Na Co Co Sn
NaCo2Sn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaCo2Sn cluster. Na(1) is bonded in a 3-coordinate geometry to one Co(1), one Co(2), and one Sn(1) atom. The Na(1)-Co(1) bond length is 1.25 Å. The Na(1)-Co(2) bond length is 1.57 Å. The Na(1)-Sn(1) bond length is 2.08 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a single-bond geometry to one Na(1) atom. In the second Co site, Co(2) is bonded in a single-bond geometry to one Na(1) atom. Sn(1) is bonded in a single-bond geometry to one Na(1) atom.
