Methyl cyanide and NN-dimethylacetamide complexes of thorium and uranium tetrahalides, uranyl chloride, and uranyl bromide
The tetrachloride and tetrabromide of thorium and of uranium react at room temperature with anhydrous methyl cyanide to form the complexes MX4,4CH3CN (M = Th and U; X = Cl and Br). The tetrabromide complexes react with NN-dimethylacetamide (DMA) to form the compounds MBr4,4DMA. Methyl cyanide and DMA complexes of uranyl chloride and uranyl bromide, UO2Cl2,CH3CN and UO2X2,2DMA (X = Cl and Br) have also been prepared. Some chemical properties, infrared spectra, and magnetic susceptibilities are reported for these complexes.
