Abstract

The reaction between the chelating amino bisphenole ligand (ONOO)H₂ (1) [ONOO = MeOCH₂ CH₂ N {CH₂ - (2 - O - C₆ H₂ - Bu₂^t - 3, 5)}₂] and (ONNO)H₂ (2) [ONNO = Me₂ N CH₂ CH₂ N {CH₂ - (2 - O - C₆ H₂ - Bu₂^t - 3, 5)}₂] with an excess of NaH gives the corresponding bis-sodium salts 3 and 4 quantitatively.The salts were reacted with thorium tetrachloride at room temperature to obtain the corresponding (ONOO)ThCl₂ (5) and (ONNO)ThCl₂ (6) complexes.However, ThCl₄ and UCl₄ react with (3) at higher temperatures to give the corresponding isomorphous homoleptic complexes (ONOO)₂Th (7) and (ONOO)₂U (8).We have also synthesized and characterized a thorium salicylaldiminato complex L₃ThCl (11) [L = (C₆ H₅) NCH (2 - O - C₆ H₂ - Bu₂^t - 3, 5)], in order to study the effect of the bridged ligand on the molecular structure.
