A convenient synthesis of antimony sulfide and antimony phosphate nanorods using single source dithiolatoantimony(III) dialkyldithiophosphate precursors

Treatment of ethane-1,2-dithiolatoantimony(III) chloride, with sodium dialkyldithiophosphates, NaS2P(OR)2 (R = Me, Et, Prn and Pri) afforded complexes of the composition, which have been characterized by elemental analyses, IR and NMR (1H and 31P{1H}) spectroscopy. Thermal behavior of the complexes has been studied by thermogravimetric analyses. The solvothermal decomposition of the above complexes in ethylene glycol yielded Sb2S3 nanorods whereas the pyrolysis of (R = Me or Et) in a furnace in a temperature range of 300–500 °C gave SbPO4 nanorods. The as-prepared nanocrystallites were characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray analysis, UV–Vis, photoluminescence and Raman spectroscopic techniques.
