Co2P is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 5-coordinate geometry to five equivalent P(1) atoms. In the second Co site, Co(2) is bonded to four equivalent P(1) atoms to form a mixture of distorted corner and edge-sharing CoP4 tetrahedra. P(1) is bonded in a 9-coordinate geometry to four equivalent Co(2) and five equivalent Co(1) atoms.
Co2P is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 5-coordinate geometry to five equivalent P(1) atoms. There are a spread of Co(1)-P(1) bond distances ranging from 2.26-2.48 Å. In the second Co site, Co(2) is bonded to four equivalent P(1) atoms to form a mixture of distorted corner and edge-sharing CoP4 tetrahedra. There are a spread of Co(2)-P(1) bond distances ranging from 2.13-2.22 Å. P(1) is bonded in a 9-coordinate geometry to four equivalent Co(2) and five equivalent Co(1) atoms.
