RbLaMo3 crystallizes in the trigonal R3m space group. Rb(1) is bonded to six equivalent Mo(1) atoms to form RbMo6 octahedra that share corners with six equivalent Rb(1)Mo6 octahedra and faces with eight equivalent La(1)Mo12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.17 Å) and three longer (2.72 Å) Rb(1)-Mo(1) bond lengths. La(1) is bonded to twelve equivalent Mo(1) atoms to form distorted LaMo12 cuboctahedra that share corners with twelve equivalent La(1)Mo12 cuboctahedra, faces with six equivalent La(1)Mo12 cuboctahedra, and faces with eight equivalent Rb(1)Mo6 octahedra. There are a spread of La(1)-Mo(1) bond distances ranging from 3.06-3.85 Å. Mo(1) is bonded in a 1-coordinate geometry to two equivalent Rb(1) and four equivalent La(1) atoms.
