We offer sui-generis strategy for synthesis of nanosized chalcogenide semiconductors in polymer matrix by a novel polymer-inorganic solid-state reaction. In our previous report, the rationale of this strategy has been successfully established by the solid-state reaction between CdI2 and an intentionally chosen engineering thermoplastic, namely, polyphenylene sulphide (PPS). In the pursuit of this work, we explored the possibility of using other cadmium salts viz cadmium nitrate, cadmium chloride and cadmium acetate in place of cadmium iodide for the envisaged solidstate reaction with PPS. All the reactions were carried out at the melting temperature of PPS (285oC) in 1:1 and 10:1 molar ratios of polymer to cadmium salt. The resultant products were characterised by XRD, TEM-SAED and DRS. It is observed that only cadmium nitrate yielded CdS nanocrystallites (average size of 15nm) entrapped in modified polymer matrix in a competing behaviour with cadmium iodide when reacted in 10:1 molar ratio while (i) cadmium acetate leads to the formation of only cadmium oxide and (ii) cadmium chloride exhibits grossly incomplete solid state reaction yielding understated quantity of CdS when reacted with PPS.

Crystals of the complexes [CdI2 · C6H12S3]2 (1) and [Hg(C6H12S3)2](HgI3)2 (2) were obtained by diffusion of 1,4,7-trithiacyclononane (9 S 3) in ethanol into aqueous solutions of cadmium iodide and mercuric iodide/potassium iodide, resp. Both compounds crystallize monoclinically,1: space group P21/n, Z = 4, a = 1207.1(5), b = 909.9(2), c = 1240.3(7) pm, β = 92.59(9)°; 2: P21/c, Z = 2, a = 804.7(6), b = 934.0(6), c = 2167.9(4) pm, β = 94.34(7)°. 1 is dimeric, consisting of two [CdI2 · 9S3] units, connected via iodine bridges. Crystals of 2 contain sandwich-like cations [Hg(9S3)2]2+ and [HgI3]- anions, forming chains via Hg ··· S and Hg ··· I bridges.

Infrared spectra and thermogravimetric (t.g.a.) and differential thermal (d.t.a.) analyses are reported for Cd(OH)2 obtained by the action of dilute ammonia solution on aqueous solutions of cadmium chloride, sulfate, and nitrate. The analyses indicate that the precipitated cadmium hydroxide from these solutions is often admixed with basic salts.
