Abstract

The reaction between the chelating amino bisphenole ligand (ONOO)H2 (1) [ONOO = MeOCH2 CH2 N {CH2 - (2 - O - C6 H2 - Bu2t - 3, 5)}2] and (ONNO)H2 (2) [ONNO = Me2 N CH2 CH2 N {CH2 - (2 - O - C6 H2 - Bu2t - 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 - Bu2t - 3, 5)], in order to study the effect of the bridged ligand on the molecular structure.
