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 7-coordinate geometry to two equivalent K(1), one Re(1), and four equivalent Re(2) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to two equivalent K(2), two equivalent Re(1), and two equivalent Re(2) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a distorted q6 geometry to three equivalent K(1), six equivalent K(2), and two equivalent Re(1) atoms. In the second Re site, Re(2) is bonded in a distorted q6 geometry to three equivalent K(2), six equivalent K(1), and two equivalent Re(2) atoms.
