Abstract

Abstract The dinucleating ligand 1, 2-bis (3, 5-di-tert-butyl-2-hydroxyphenyl) oxamide [H 4 (bbpo)] has been synthesized. From its reaction with GaCl 3 or FeCl 3 in CH 3 OH/NaOH the salts [N (nBu) 4] 2 [M III 2 (bbpo) Cl 4][M= Ga (1), Fe (2)] have been isolated as crystalline solids upon addition of [N (nBu) 4] Cl. Complexes 1 and 2 have been characterized by single-crystal X-ray crystallography. Cyclic voltammetry established that both species ...
