stoichiometry. The reaction of cadmium acetate with [(3,5-Me(2)-C(5)H(3)N)(2)Zn(SSiMe(3))(2)], PhSSiMe(3), and P(n)()Pr(3) affords the larger nanocluster [Zn(2.3)Cd(14.7)S(4)(SPh)(26)(P(n)()Pr(3))(2)] (6). The incorporation of Zn(II) into Cd(10)E} (E = Se, Te) and Zn(II) or Cd(II) into Hg(10)Se} nanoclusters results in a significant blue shift in the energy of the first "excitonic" transition.
