The material structure described by Mo2Rh2C is H-Phase-like structured and crystallizes in the trigonal R-3m space group. Mo(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) and three equivalent C(1) atoms. Rh(1) is bonded to three equivalent Mo(1) and nine equivalent Rh(1) atoms to form distorted RhMo3Rh9 cuboctahedra that share corners with six equivalent Rh(1)Mo3Rh9 cuboctahedra, corners with six equivalent C(1)Mo6 octahedra, edges with twelve equivalent Rh(1)Mo3Rh9 cuboctahedra, faces with twelve equivalent Rh(1)Mo3Rh9 cuboctahedra, and  a faceface with one C(1)Mo6 octahedra. The corner-sharing octahedral tilt angles are 43°. C(1) is bonded to six equivalent Mo(1) atoms to form CMo6 octahedra that share corners with twelve equivalent Rh(1)Mo3Rh9 cuboctahedra, edges with six equivalent C(1)Mo6 octahedra, and faces with two equivalent Rh(1)Mo3Rh9 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
