The authors describe the preparation of the solid-state compounds ZnS, ZnSe, CdS, CdSe, CdTe, and HgTe from the corresponding M(ER){sub 2} compounds (M = Zn, Cd, Hg; E = S, Se, Te; R = n-butyl,phenyl) and/or phosphine complexes thereof. The authors have isolated members of two different families of phosphine complexes. In the first the bidentate phosphine 1,2-bis(diethylphosphino)ethane (DEPE) is coordinated to the M(ER){sub 2} nucleus in a 1:2 ratio, and a coordination polymer is formed. In the second the DEPE/M(ER){sub 2} ratio is unity, and a dimeric compound is formed. They show that pyrolysis of these compounds in the solid state yields the bulk solid-state compound and that pyrolysis in solution yields the same solid-state compound, but in the form of nanometer-sized particles. Nanoclusters of HgTe are similarly formed by solution-phase photolysis of Hg(TeBu){sub 2}.
