KRh2Pb crystallizes in the triclinic P1 space group. K(1) is bonded in a 2-coordinate geometry to one Rh(1), two equivalent Rh(2), and one Pb(1) atom. The K(1)-Rh(1) bond length is 2.47 Å. There is one shorter (3.23 Å) and one longer (3.64 Å) K(1)-Rh(2) bond length. The K(1)-Pb(1) bond length is 1.70 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 1-coordinate geometry to one K(1) and one Rh(2) atom. The Rh(1)-Rh(2) bond length is 2.26 Å. In the second Rh site, Rh(2) is bonded in a 5-coordinate geometry to two equivalent K(1), one Rh(1), and two equivalent Pb(1) atoms. There is one shorter (2.47 Å) and one longer (2.98 Å) Rh(2)-Pb(1) bond length. Pb(1) is bonded in a single-bond geometry to one K(1) and two equivalent Rh(2) atoms.
