NaRh2Co crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaRh2Co cluster. Na(1) is bonded in a distorted water-like geometry to one Rh(1), one Rh(2), and one Co(1) atom. The Na(1)-Rh(1) bond length is 0.34 Å. The Na(1)-Rh(2) bond length is 0.61 Å. The Na(1)-Co(1) bond length is 0.34 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Na(1) atom. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one Na(1) atom. Co(1) is bonded in a single-bond geometry to one Na(1) atom.
