K2Ag crystallizes in the triclinic P1 space group. There are six inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one K(3) and two equivalent K(4) atoms. The K(1)-K(3) bond length is 0.47 Å. There is one shorter (2.32 Å) and one longer (3.45 Å) K(1)-K(4) bond length. In the second K site, K(2) is bonded in a 3-coordinate geometry to two equivalent K(4), one Ag(1), one Ag(2), and one Ag(3) atom. There is one shorter (2.72 Å) and one longer (3.73 Å) K(2)-K(4) bond length. The K(2)-Ag(1) bond length is 2.69 Å. The K(2)-Ag(2) bond length is 3.35 Å. The K(2)-Ag(3) bond length is 3.32 Å. In the third K site, K(3) is bonded in a distorted single-bond geometry to one K(1) and two equivalent K(4) atoms. There is one shorter (2.19 Å) and one longer (3.37 Å) K(3)-K(4) bond length. In the fourth K site, K(4) is bonded in a 10-coordinate geometry to one K(5), one K(6), two equivalent K(1), two equivalent K(2), two equivalent K(3), one Ag(2), and one Ag(3) atom. The K(4)-K(5) bond length is 2.74 Å. The K(4)-K(6) bond length is 3.29 Å. The K(4)-Ag(2) bond length is 4.08 Å. The K(4)-Ag(3) bond length is 4.16 Å. In the fifth K site, K(5) is bonded in a 1-coordinate geometry to one K(4), one Ag(1), and one Ag(3) atom. The K(5)-Ag(1) bond length is 3.72 Å. The K(5)-Ag(3) bond length is 3.33 Å. In the sixth K site, K(6) is bonded in a distorted single-bond geometry to one K(4), one Ag(3), and two equivalent Ag(1) atoms. The K(6)-Ag(3) bond length is 3.53 Å. There is one shorter (2.17 Å) and one longer (3.35 Å) K(6)-Ag(1) bond length. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to one K(2), one K(5), and two equivalent K(6) atoms. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one K(2) and one K(4) atom. In the third Ag site, Ag(3) is bonded in a 3-coordinate geometry to one K(2), one K(4), one K(5), and one K(6) atom.
