The compound described by Rb3Tc is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 4-coordinate geometry to four equivalent Rb(2) and four equivalent Tc(1) atoms. In the second Rb site, Rb(2) is bonded to eight equivalent Rb(1) and four equivalent Tc(1) atoms to form RbRb8Tc4 cuboctahedra that share corners with four equivalent Rb(2)Rb8Tc4 cuboctahedra, corners with eight equivalent Tc(1)Rb12 cuboctahedra, edges with eight equivalent Rb(2)Rb8Tc4 cuboctahedra, faces with four equivalent Rb(2)Rb8Tc4 cuboctahedra, and faces with six equivalent Tc(1)Rb12 cuboctahedra. Tc(1) is bonded to four equivalent Rb(2) and eight equivalent Rb(1) atoms to form TcRb12 cuboctahedra that share corners with four equivalent Tc(1)Rb12 cuboctahedra, corners with eight equivalent Rb(2)Rb8Tc4 cuboctahedra, edges with eight equivalent Tc(1)Rb12 cuboctahedra, faces with four equivalent Tc(1)Rb12 cuboctahedra, and faces with six equivalent Rb(2)Rb8Tc4 cuboctahedra. is represented by the CIF card [CIF]
