CeRu2CP crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 4-coordinate geometry to four equivalent C(1) and three equivalent P(1) atoms. Ru(1) is bonded in a distorted single-bond geometry to one C(1) and three equivalent P(1) atoms. C(1) is bonded to four equivalent Ce(1) and two equivalent Ru(1) atoms to form a mixture of corner and edge-sharing CCe4Ru2 octahedra. The corner-sharing octahedral tilt angles are 23°. P(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent Ru(1) atoms.
CeRu2CP crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 4-coordinate geometry to four equivalent C(1) and three equivalent P(1) atoms. All Ce(1)-C(1) bond lengths are 2.68 Å. There is one shorter (3.06 Å) and two longer (3.14 Å) Ce(1)-P(1) bond lengths. Ru(1) is bonded in a distorted single-bond geometry to one C(1) and three equivalent P(1) atoms. The Ru(1)-C(1) bond length is 1.89 Å. There is one shorter (2.46 Å) and two longer (2.48 Å) Ru(1)-P(1) bond lengths. C(1) is bonded to four equivalent Ce(1) and two equivalent Ru(1) atoms to form a mixture of corner and edge-sharing CCe4Ru2 octahedra. The corner-sharing octahedral tilt angles are 23°.
