Pa3Re is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Pa sites. In the first Pa site, Pa(1) is bonded to four equivalent Pa(2) and four equivalent Re(1) atoms to form a mixture of distorted edge, face, and corner-sharing PaPa4Re4 tetrahedra. In the second Pa site, Pa(2) is bonded in a 14-coordinate geometry to eight equivalent Pa(1) and six equivalent Re(1) atoms. Re(1) is bonded in a distorted body-centered cubic geometry to six equivalent Pa(2) and eight equivalent Pa(1) atoms.

In the first Pa site, Pa(1) is bonded to four equivalent Pa(2) and four equivalent Re(1) atoms to form a mixture of distorted edge, face, and corner-sharing PaPa4Re4 tetrahedra. All Pa(1)-Pa(2) bond lengths are 3.05 Å. All Pa(1)-Re(1) bond lengths are 3.05 Å. In the second Pa site, Pa(2) is bonded in a 14-coordinate geometry to eight equivalent Pa(1) and six equivalent Re(1) atoms. All Pa(2)-Re(1) bond lengths are 3.53 Å. Re(1) is bonded in a distorted body-centered cubic geometry to six equivalent Pa(2) and eight equivalent Pa(1) atoms.
