The structure described by ThTc3 is alpha bismuth trifluoride structured and crystallizes in the monoclinic C2/m space group. Th(1) is bonded in a distorted body-centered cubic geometry to six equivalent Tc(2) and eight equivalent Tc(1) atoms. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded to four equivalent Th(1) and four equivalent Tc(2) atoms to form a mixture of distorted corner, face, and edge-sharing TcTh4Tc4 tetrahedra. In the second Tc site, Tc(2) is bonded in a 14-coordinate geometry to six equivalent Th(1) and eight equivalent Tc(1) atoms. is represented by the CIF file [CIF]
