| Abstract: | A series of methylbismuth(III)O,O‐alkylenedithiophosphates of the type [where G = CH2CH(CH3) ( 1 ), (CH2)4 ( 2 ), CH2CH2CH(CH3) ( 3 ), CH(CH3)CH(CH3) ( 4 ), CH2CHCH2CH3 ( 5 ), CH(CH3)CH2C(CH3)2 ( 6 ) and C(CH3)2C(CH3)2 ( 7 )] have been isolated by the reaction of methylbismuth(III) dichloride with potassium salt of O,O‐alkylenedithiophosphoric acids in 1:2 molar ratio in anhydrous benzene. These newly synthesized derivatives were characterized by elemental analyses, FT IR and multinuclear NMR (1H, 13C and 31P) spectral studies. Thermogravimetric analysis of 6 has shown a single‐step decomposition of complex to Bi2S3 at 154.3 °C. Transformation of 2 and 6 to pure Bi2S3 was carried out successfully at refluxing xylene temperature (142 °C) as revealed by XRD and SEM analyses. Copyright © 2006 John Wiley & Sons, Ltd. |
