RbTc3Te is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Rb(1) is bonded to twelve equivalent Tc(1) atoms to form RbTc12 cuboctahedra that share corners with twelve equivalent Rb(1)Tc12 cuboctahedra, faces with six equivalent Rb(1)Tc12 cuboctahedra, and faces with eight equivalent Te(1)Tc6 octahedra. There are a spread of Rb(1)-Tc(1) bond distances ranging from 3.43-3.70 Å. Tc(1) is bonded to four equivalent Rb(1) and two equivalent Te(1) atoms to form a mixture of distorted edge, face, and corner-sharing TcRb4Te2 octahedra. The corner-sharing octahedral tilt angles range from 0-61°. There is one shorter (2.42 Å) and one longer (2.62 Å) Tc(1)-Te(1) bond length. Te(1) is bonded to six equivalent Tc(1) atoms to form TeTc6 octahedra that share corners with six equivalent Te(1)Tc6 octahedra and faces with eight equivalent Rb(1)Tc12 cuboctahedra. The corner-sharing octahedra are not tilted.
