The compound described by Ho2Mo2C3 crystallizes in the monoclinic C2/m space group. Ho(1) is bonded to two equivalent C(2) and three equivalent C(1) atoms to form a mixture of corner and edge-sharing HoC5 square pyramids. Mo(1) is bonded in a distorted see-saw-like geometry to one C(2) and three equivalent C(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded to three equivalent Ho(1) and three equivalent Mo(1) atoms to form CHo3Mo3 octahedra that share corners with three equivalent C(2)Ho4Mo2 octahedra, edges with three equivalent C(2)Ho4Mo2 octahedra, and edges with six equivalent C(1)Ho3Mo3 octahedra. The corner-sharing octahedral tilt angles range from 11-28°. In the second C site, C(2) is bonded to four equivalent Ho(1) and two equivalent Mo(1) atoms to form CHo4Mo2 octahedra that share corners with six equivalent C(1)Ho3Mo3 octahedra, edges with two equivalent C(2)Ho4Mo2 octahedra, and edges with six equivalent C(1)Ho3Mo3 octahedra. The corner-sharing octahedral tilt angles range from 11-28°. is represented by the Crystallographic Information File (CIF) [CIF]
