Abstract Organosols of NiS, PdS, and MnS in N,N-dimethylformamide were prepared by reaction of the metal acetate with H2S. Organosols of mixed-metal sulfides (Zn x Cd1−x S, Hg x Cd1−x S, Hg x Cu1−x S, Cd x Mn1−x S, Hg x Mn1−x S, Hg x Cd1−x S, and Mn x Zn1−x S) were similarly obtained by reaction of mixtures of the metal salts with H2S. The organosol of Zn0.5Cd0.5S contained particle with two particle size distributions centered at 6.5 nm and 29 nm, as revealed by Ar laser-scattering analysis. The metal sulfides are recovered by addition of Et2O to the organosols. Zn x Cd1−x S thus obtained shows magnetic susceptibility in the range 0.5×10−6–2.3×10−6 emug−1 depending on thex value. Addition of polymers to the organosols affords semiconducting films of metal sulfide-polymer composites.
