Materials Data on Mo2Ir2C by Materials Project
Mo2Ir2C crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Mo is bonded to nine equivalent Mo and three equivalent Ir atoms to form MoMo9Ir3 cuboctahedra that share corners with six equivalent MoMo9Ir3 cuboctahedra, corners with six equivalent CIr6 octahedra, edges with twelve equivalent MoMo9Ir3 cuboctahedra, faces with twelve equivalent MoMo9Ir3 cuboctahedra, and a faceface with one CIr6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are six shorter (2.85 Å) and three longer (2.95 Å) Mo–Mo bond lengths. All Mo–Ir bond lengths are 2.78 Å. Ir is bonded in a 3-coordinate geometry to three equivalent Mo and three equivalent C atoms. All Ir–C bond lengths are 2.14 Å. C is bonded to six equivalent Ir atoms to form CIr6 octahedra that share corners with twelve equivalent MoMo9Ir3 cuboctahedra, edges with six equivalent CIr6 octahedra, and faces with two equivalent MoMo9Ir3 cuboctahedra.
