The structure described by Ta is alpha Po structured and crystallizes in the cubic Pm-3m space group. Ta(1) is bonded to six equivalent Ta(1) atoms to form a mixture of edge and corner-sharing TaTa6 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
