Rh2CoP is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Rh2CoP clusters. Rh(1) is bonded in a 3-coordinate geometry to one Rh(1), one Co(1), and one P(1) atom. The Rh(1)-Rh(1) bond length is 0.62 Å. The Rh(1)-Co(1) bond length is 0.91 Å. The Rh(1)-P(1) bond length is 0.91 Å. Co(1) is bonded in a distorted single-bond geometry to two equivalent Rh(1) and one P(1) atom. The Co(1)-P(1) bond length is 0.62 Å. P(1) is bonded in a distorted single-bond geometry to two equivalent Rh(1) and one Co(1) atom.
