The compound described by Mo2Ir2C crystallizes in the trigonal R-3m space group. Mo(1) is bonded to nine equivalent Mo(1) and three equivalent Ir(1) atoms to form MoMo9Ir3 cuboctahedra that share corners with six equivalent Mo(1)Mo9Ir3 cuboctahedra, corners with six equivalent C(1)Ir6 octahedra, edges with twelve equivalent Mo(1)Mo9Ir3 cuboctahedra, faces with twelve equivalent Mo(1)Mo9Ir3 cuboctahedra, and  a faceface with one C(1)Ir6 octahedra. The corner-sharing octahedral tilt angles are 42°. Ir(1) is bonded in a 3-coordinate geometry to three equivalent Mo(1) and three equivalent C(1) atoms. C(1) is bonded to six equivalent Ir(1) atoms to form CIr6 octahedra that share corners with twelve equivalent Mo(1)Mo9Ir3 cuboctahedra, edges with six equivalent C(1)Ir6 octahedra, and faces with two equivalent Mo(1)Mo9Ir3 cuboctahedra. is represented by the CIF card [CIF]
