The structure described by PaTc3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. Pa(1) is bonded to four equivalent Tc(2) and eight equivalent Tc(1) atoms to form PaTc12 cuboctahedra that share corners with four equivalent Pa(1)Tc12 cuboctahedra, corners with eight equivalent Tc(2)Pa4Tc8 cuboctahedra, edges with eight equivalent Pa(1)Tc12 cuboctahedra, edges with sixteen equivalent Tc(1)Pa4Tc8 cuboctahedra, faces with four equivalent Pa(1)Tc12 cuboctahedra, faces with six equivalent Tc(2)Pa4Tc8 cuboctahedra, and faces with eight equivalent Tc(1)Pa4Tc8 cuboctahedra. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded to four equivalent Pa(1), four equivalent Tc(1), and four equivalent Tc(2) atoms to form distorted TcPa4Tc8 cuboctahedra that share corners with twelve equivalent Tc(1)Pa4Tc8 cuboctahedra, edges with eight equivalent Pa(1)Tc12 cuboctahedra, edges with eight equivalent Tc(1)Pa4Tc8 cuboctahedra, edges with eight equivalent Tc(2)Pa4Tc8 cuboctahedra, faces with four equivalent Pa(1)Tc12 cuboctahedra, faces with four equivalent Tc(2)Pa4Tc8 cuboctahedra, and faces with ten equivalent Tc(1)Pa4Tc8 cuboctahedra. In the second Tc site, Tc(2) is bonded to four equivalent Pa(1) and eight equivalent Tc(1) atoms to form TcPa4Tc8 cuboctahedra that share corners with four equivalent Tc(2)Pa4Tc8 cuboctahedra, corners with eight equivalent Pa(1)Tc12 cuboctahedra, edges with eight equivalent Tc(2)Pa4Tc8 cuboctahedra, edges with sixteen equivalent Tc(1)Pa4Tc8 cuboctahedra, faces with four equivalent Tc(2)Pa4Tc8 cuboctahedra, faces with six equivalent Pa(1)Tc12 cuboctahedra, and faces with eight equivalent Tc(1)Pa4Tc8 cuboctahedra. is represented by the CIF file [CIF]
