NaTa3 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 Ta(2) and eight equivalent Ta(1) atoms. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded to four equivalent Na(1) and four equivalent Ta(2) atoms to form a mixture of distorted edge, face, and corner-sharing TaNa4Ta4 tetrahedra. In the second Ta site, Ta(2) is bonded in a 14-coordinate geometry to six equivalent Na(1) and eight equivalent Ta(1) atoms.
