摘要

The research work, performed during the course of present investigations is concerned with the synthesis, physico-chemical [elemental analysis and melting points determinations], spectral [IR, Far-IR, multinuclear (C-13 and Sn-119) solid-state NMR], powder XRD and thermal studies on 1,3-dithia-2-stannacyclopentane(IV) derivatives with alkyldithiocarbonates. The derivatives, [(CH2S)(2)Sn(S2COR)Cl] and [(CH2S)(2)Sn(S2COR)(2)] have been synthesized by the reaction of 1,3-dithia-2-stannacyclopentane(IV) dichloride with potassium alkyldithiocarbonates in 1:1 and 1:2 stoichiometry, respectively. Thermal decomposition study provides significant information about the formation of tin sulfide (SnS2) which has a number of commercial applications in various fields. Crystallite size of the derivatives has been found in nano range (similar to 132 nm) with the help of powder XRD studies. Sideband patterns obtained in our respective derivatives indicate distorted geometry and increased shielding of tin in solid state as compared to solution state Sn-119 NMR, could be an indication of high electron density at tin atom.
