K Zn Pb Pb
KZnPb2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KZnPb2 cluster. K(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one Pb(1) atom. The K(1)-Zn(1) bond length is 1.92 Å. The K(1)-Pb(1) bond length is 2.02 Å. Zn(1) is bonded in a bent 120 degrees geometry to one K(1) and one Pb(2) atom. The Zn(1)-Pb(2) bond length is 1.20 Å. 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 Zn(1) atom.
