NaTc3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Na(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 Na(1) and four equivalent Tc(2) atoms to form a mixture of distorted edge, face, and corner-sharing TcNa4Tc4 tetrahedra. In the second Tc site, Tc(2) is bonded in a 14-coordinate geometry to six equivalent Na(1) and eight equivalent Tc(1) atoms.
