HoRu2CP crystallizes in the orthorhombic Cmcm space group. Ho(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 Ho(1) and two equivalent Ru(1) atoms to form a mixture of corner and edge-sharing CHo4Ru2 octahedra. The corner-sharing octahedral tilt angles are 21°. P(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent Ru(1) atoms.
HoRu2CP crystallizes in the orthorhombic Cmcm space group. Ho(1) is bonded in a 4-coordinate geometry to four equivalent C(1) and three equivalent P(1) atoms. All Ho(1)-C(1) bond lengths are 2.63 Å. There is one shorter (3.06 Å) and two longer (3.11 Å) Ho(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 1.86 Å. There is one shorter (2.42 Å) and two longer (2.46 Å) Ru(1)-P(1) bond lengths. C(1) is bonded to four equivalent Ho(1) and two equivalent Ru(1) atoms to form a mixture of corner and edge-sharing CHo4Ru2 octahedra. The corner-sharing octahedral tilt angles are 21°.
