CeP2 crystallizes in the monoclinic P2_1/c space group. Ce(1) is bonded in a 9-coordinate geometry to four equivalent P(2) and five equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to five equivalent Ce(1) and one P(2) atom to form a mixture of distorted corner and edge-sharing PCe5P pentagonal pyramids. In the second P site, P(2) is bonded in a 6-coordinate geometry to four equivalent Ce(1), one P(1), and one P(2) atom.
CeP2 crystallizes in the monoclinic P2_1/c space group. Ce(1) is bonded in a 9-coordinate geometry to four equivalent P(2) and five equivalent P(1) atoms. There are a spread of Ce(1)-P(2) bond distances ranging from 2.98-3.16 Å. There are a spread of Ce(1)-P(1) bond distances ranging from 2.91-3.15 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded to five equivalent Ce(1) and one P(2) atom to form a mixture of distorted corner and edge-sharing PCe5P pentagonal pyramids. The P(1)-P(2) bond length is 2.21 Å. In the second P site, P(2) is bonded in a 6-coordinate geometry to four equivalent Ce(1), one P(1), and one P(2) atom. The P(2)-P(2) bond length is 2.26 Å.
