A complex N,N-dibutyl dithiocarbamate antimony(SDBC) was synthesized by one-step method.The results of IR,13C-NMR,EA and ICP test indicated that the composition and structure of the product accord with the target product and the coordination number of SDBC is 3.Moreover,the DSC curve showed a single and narrow peak at 73 ℃,which indicates that the melting point of the product is 73 ℃ and the purity of the product is extremely high.Finally,the TGA curve showed that there is an obvious weight loss when the te...
