TcRh crystallizes in the hexagonal P-6m2 space group. Tc(1) is bonded to six equivalent Tc(1) and six equivalent Rh(1) atoms to form distorted TcTc6Rh6 cuboctahedra that share corners with eighteen equivalent Tc(1)Tc6Rh6 cuboctahedra, edges with six equivalent Tc(1)Tc6Rh6 cuboctahedra, edges with twelve equivalent Rh(1)Tc6Rh6 cuboctahedra, faces with eight equivalent Tc(1)Tc6Rh6 cuboctahedra, and faces with twelve equivalent Rh(1)Tc6Rh6 cuboctahedra. Rh(1) is bonded to six equivalent Tc(1) and six equivalent Rh(1) atoms to form distorted RhTc6Rh6 cuboctahedra that share corners with eighteen equivalent Rh(1)Tc6Rh6 cuboctahedra, edges with six equivalent Rh(1)Tc6Rh6 cuboctahedra, edges with twelve equivalent Tc(1)Tc6Rh6 cuboctahedra, faces with eight equivalent Rh(1)Tc6Rh6 cuboctahedra, and faces with twelve equivalent Tc(1)Tc6Rh6 cuboctahedra.
