CoP3 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CoP3 clusters. Co(1) is bonded in a 3-coordinate geometry to one P(1) and two equivalent P(2) atoms. The Co(1)-P(1) bond length is 0.51 Å. Both Co(1)-P(2) bond lengths are 0.89 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 single-bond geometry to one Co(1) atom.
