The crystal structure described by K2ReF8 crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 11-coordinate geometry to one F(1), two equivalent F(2), two equivalent F(3), two equivalent F(4), and four equivalent F(5) atoms. In the second K site, K(2) is bonded in a 11-coordinate geometry to one F(2), two equivalent F(1), two equivalent F(3), two equivalent F(5), and four equivalent F(4) atoms. Re(1) is bonded in a 8-coordinate geometry to one F(1), one F(2), two equivalent F(3), two equivalent F(4), and two equivalent F(5) atoms. There are five inequivalent F sites. In the first F site, F(5) is bonded to one K(2), two equivalent K(1), and one Re(1) atom to form a mixture of distorted corner and edge-sharing FK3Re tetrahedra. In the second F site, F(1) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Re(1) atom. In the third F site, F(2) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one Re(1) atom. In the fourth F site, F(3) is bonded in a distorted trigonal non-coplanar geometry to one K(1), one K(2), and one Re(1) atom. In the fifth F site, F(4) is bonded to one K(1), two equivalent K(2), and one Re(1) atom to form a mixture of distorted corner and edge-sharing FK3Re tetrahedra. is represented by the CIF card [CIF]
