Abstract

The first nine-atom deltahedral clusters of lead in the solid state are found in the Zintl-phase K(4)Pb(9). The compound crystallizes in the monoclinic space group P2(1)/m, Z = 4, with a = 9.648(3) Å, b = 13.243(5) Å, c = 15.909(8) Å, and beta = 103.24(4) degrees. The isolated Pb(9)(4)(-) clusters are of two different geometries, a monocapped square antiprism and an elongated tricapped trigonal prism.
