Abstract
The first nine-atom deltahedral clusters of lead in the solid state ar e found in the Zintl-phase K4Pb9. The compound crystallizes in the mon oclinic space group P2(1)/m, Z = 4, with a = 9.648(3) Angstrom, b = 13 .243(5) Angstrom, c = 15.909(8) Angstrom, and beta = 103.24(4)degrees. The isolated Pb-9(4-) clusters are of two different geometries, a mon ocapped square antiprism and an elongated tricapped trigonal prism.
