HoRu2SiC crystallizes in the orthorhombic Cmcm space group. Ho(1) is bonded in a 4-coordinate geometry to three equivalent Si(1) and four equivalent C(1) atoms. Ru(1) is bonded in a 4-coordinate geometry to three equivalent Si(1) and one C(1) atom. Si(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent Ru(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 23°.
