K Mg Ag Ag
KMgAg2 crystallizes in the triclinic P1 space group. K(1) is bonded in a 5-coordinate geometry to two equivalent K(1), one Mg(1), one Ag(1), and one Ag(2) atom. Both K(1)-K(1) bond lengths are 3.23 Å. The K(1)-Mg(1) bond length is 3.24 Å. The K(1)-Ag(1) bond length is 3.75 Å. The K(1)-Ag(2) bond length is 3.75 Å. Mg(1) is bonded in a 1-coordinate geometry to one K(1) and one Ag(2) atom. The Mg(1)-Ag(2) bond length is 1.74 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one K(1) and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 0.78 Å. In the second Ag site, Ag(2) is bonded in a distorted L-shaped geometry to one K(1), one Mg(1), and one Ag(1) atom.
