KPb2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. K(1) is bonded in a 12-coordinate geometry to three equivalent Pb(1) and nine equivalent Pb(2) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to six equivalent K(1) and six equivalent Pb(2) atoms to form a mixture of corner, edge, and face-sharing PbK6Pb6 cuboctahedra. In the second Pb site, Pb(2) is bonded to six equivalent K(1), two equivalent Pb(1), and four equivalent Pb(2) atoms to form a mixture of distorted corner, edge, and face-sharing PbK6Pb6 cuboctahedra.
KPb2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. K(1) is bonded in a 12-coordinate geometry to three equivalent Pb(1) and nine equivalent Pb(2) atoms. All K(1)-Pb(1) bond lengths are 3.98 Å. There are three shorter (3.86 Å) and six longer (3.91 Å) K(1)-Pb(2) bond lengths. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to six equivalent K(1) and six equivalent Pb(2) atoms to form a mixture of corner, edge, and face-sharing PbK6Pb6 cuboctahedra. All Pb(1)-Pb(2) bond lengths are 3.30 Å. In the second Pb site, Pb(2) is bonded to six equivalent K(1), two equivalent Pb(1), and four equivalent Pb(2) atoms to form a mixture of distorted corner, edge, and face-sharing PbK6Pb6 cuboctahedra. There are two shorter (3.35 Å) and two longer (3.43 Å) Pb(2)-Pb(2) bond lengths.
