Na Co P P
NaCoP2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaCoP2 cluster. Na(1) is bonded in a 2-coordinate geometry to one Co(1) and one P(2) atom. The Na(1)-Co(1) bond length is 1.10 Å. The Na(1)-P(2) bond length is 0.82 Å. Co(1) is bonded in a 3-coordinate geometry to one Na(1), one P(1), and one P(2) atom. The Co(1)-P(1) bond length is 1.05 Å. The Co(1)-P(2) bond length is 1.05 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one Co(1) atom. In the second P site, P(2) is bonded in a 2-coordinate geometry to one Na(1) and one Co(1) atom.
