Complexes of uranyl chloride and thorium and uranium tetrachlorides with dicarboxylic acid amides

Abstract

NNN′N′-Tetramethyl-malonamide (TMMA), -αα-dimethylmalonamide (HMMA), -glutaramide (TMGA), and -3,3-dimethylglutaramide (HMGA) complexes with uranyl chloride and with thorium and uranium tetrachloride have been prepared in acetone. These have the compositions UO₂Cl₂,1·5TMMA (or TMGA), UO₂Cl₂,HMMA (or HMGA), ThCl₄,2TMMA, ThCl₄,1·5TMGA (HMMA or HMGA), UCl₄,1·5TMMA (TMGA or HMGA), and UCl₄,HMMA. Some chemical and physical properties of the complexes are reported.
