K3Re is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to four equivalent K(2) and four equivalent Re(1) atoms to form a mixture of distorted edge, corner, and face-sharing KK4Re4 tetrahedra. In the second K site, K(2) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. Re(1) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms.
