Co Co Si P
Co2SiP crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Co2SiP cluster. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a single-bond geometry to one P(1) atom. The Co(1)-P(1) bond length is 0.88 Å. In the second Co site, Co(2) is bonded in a 2-coordinate geometry to one Si(1) and one P(1) atom. The Co(2)-Si(1) bond length is 1.04 Å. The Co(2)-P(1) bond length is 1.36 Å. Si(1) is bonded in a distorted L-shaped geometry to one Co(2) and one P(1) atom. The Si(1)-P(1) bond length is 1.05 Å. P(1) is bonded in a 3-coordinate geometry to one Co(1), one Co(2), and one Si(1) atom.
