NaMn2Co crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaMn2Co cluster. Na(1) is bonded in a 2-coordinate geometry to one Mn(2) and one Co(1) atom. The Na(1)-Mn(2) bond length is 1.28 Å. The Na(1)-Co(1) bond length is 1.19 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one Co(1) atom. The Mn(1)-Co(1) bond length is 1.17 Å. In the second Mn site, Mn(2) is bonded in a single-bond geometry to one Na(1) and one Co(1) atom. The Mn(2)-Co(1) bond length is 0.58 Å. Co(1) is bonded in a 3-coordinate geometry to one Na(1), one Mn(1), and one Mn(2) atom.
