KAgPb2 is Ammonia-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KAgPb2 cluster. K(1) is bonded in a distorted trigonal non-coplanar geometry to one Ag(1), one Pb(1), and one Pb(2) atom. The K(1)-Ag(1) bond length is 1.05 Å. The K(1)-Pb(1) bond length is 1.05 Å. The K(1)-Pb(2) bond length is 0.96 Å. Ag(1) is bonded in a single-bond geometry to one K(1) atom. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a single-bond geometry to one K(1) atom. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one K(1) atom.
