K2ReAg crystallizes in the triclinic P1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 2-coordinate geometry to one K(2), one Re(1), and one Ag(1) atom. The K(1)-K(2) bond length is 1.08 Å. The K(1)-Re(1) bond length is 2.43 Å. The K(1)-Ag(1) bond length is 3.13 Å. In the second K site, K(2) is bonded in a distorted bent 150 degrees geometry to one K(1), one Re(1), and one Ag(1) atom. The K(2)-Re(1) bond length is 2.43 Å. The K(2)-Ag(1) bond length is 3.58 Å. Re(1) is bonded in a distorted linear geometry to one K(1), one K(2), and one Ag(1) atom. The Re(1)-Ag(1) bond length is 2.82 Å. Ag(1) is bonded in a 5-coordinate geometry to one K(1), one K(2), one Re(1), and two equivalent Ag(1) atoms. Both Ag(1)-Ag(1) bond lengths are 2.76 Å.
