TbRu2CP crystallizes in the orthorhombic Cmcm space group. Tb(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 Tb(1) and two equivalent Ru(1) atoms to form a mixture of corner and edge-sharing CTb4Ru2 octahedra. The corner-sharing octahedral tilt angles are 22°. P(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1) and six equivalent Ru(1) atoms.
TbRu2CP crystallizes in the orthorhombic Cmcm space group. Tb(1) is bonded in a 4-coordinate geometry to four equivalent C(1) and three equivalent P(1) atoms. All Tb(1)-C(1) bond lengths are 2.64 Å. There is one shorter (3.04 Å) and two longer (3.12 Å) Tb(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 1.87 Å. There is one shorter (2.43 Å) and two longer (2.46 Å) Ru(1)-P(1) bond lengths. C(1) is bonded to four equivalent Tb(1) and two equivalent Ru(1) atoms to form a mixture of corner and edge-sharing CTb4Ru2 octahedra. The corner-sharing octahedral tilt angles are 22°.
