Rb3Ti is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Rb(1) is bonded to eight equivalent Rb(1) and four equivalent Ti(1) atoms to form distorted RbRb8Ti4 cuboctahedra that share corners with twelve equivalent Rb(1)Rb8Ti4 cuboctahedra, edges with eight equivalent Ti(1)Rb12 cuboctahedra, edges with sixteen equivalent Rb(1)Rb8Ti4 cuboctahedra, faces with four equivalent Ti(1)Rb12 cuboctahedra, and faces with fourteen equivalent Rb(1)Rb8Ti4 cuboctahedra. Ti(1) is bonded to twelve equivalent Rb(1) atoms to form TiRb12 cuboctahedra that share corners with twelve equivalent Ti(1)Rb12 cuboctahedra, edges with twenty-four equivalent Rb(1)Rb8Ti4 cuboctahedra, faces with six equivalent Ti(1)Rb12 cuboctahedra, and faces with twelve equivalent Rb(1)Rb8Ti4 cuboctahedra.
