K2Re crystallizes in the hexagonal P-62m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to one Re(1) and four equivalent Re(2) atoms. In the second K site, K(2) is bonded to two equivalent Re(1) and two equivalent Re(2) atoms to form a mixture of distorted corner and edge-sharing KRe4 tetrahedra. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 9-coordinate geometry to three equivalent K(1) and six equivalent K(2) atoms. In the second Re site, Re(2) is bonded in a 9-coordinate geometry to three equivalent K(2) and six equivalent K(1) atoms.
K2Re crystallizes in the hexagonal P-62m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to one Re(1) and four equivalent Re(2) atoms. The K(1)-Re(1) bond length is 3.89 Å. All K(1)-Re(2) bond lengths are 3.76 Å. In the second K site, K(2) is bonded to two equivalent Re(1) and two equivalent Re(2) atoms to form a mixture of distorted corner and edge-sharing KRe4 tetrahedra. Both K(2)-Re(1) bond lengths are 3.45 Å. Both K(2)-Re(2) bond lengths are 3.57 Å. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 9-coordinate geometry to three equivalent K(1) and six equivalent K(2) atoms. In the second Re site, Re(2) is bonded in a 9-coordinate geometry to three equivalent K(2) and six equivalent K(1) atoms.
