solid state are found in the Zintl-phase
K4Pb9. The compound
crystallizes in the monoclinic space group
P21/m, Z = 4, with
a = 9.648(3) Å, b = 13.243(5) Å,
c = 15.909(8)
Å, and β = 103.24(4)°. The isolated
Pb94- clusters are of two
different geometries, a monocapped square antiprism
and an elongated tricapped trigonal prism.
