Abstract
The synthesis and structure of neutral and cationic aluminum compounds equipped with the intramolecular donating C(SiMe3)2SiMe2(2-C5H4N) ligand denoted by Pytsi is described. The compounds (Pytsi)AlMe2 (1), (Pytsi)AlEt2 (2), [(Pytsi)AlMe]+[MeB(C6F5)3]- (3), and [(Pytsi)AlMe(thf)]+[MeB(C6F5)3]- (3·thf) have been synthesized and characterized by standard methods, and the molecular structures of 1, 2, and 3 have been determined by single-crystal X-ray analyses. Compound 3 was obtained by an addition of 1 equiv of B(C6F5)3 to the dimethyl species 1. The salt-like title compound 3 shows a methyl group in a bridging position between Al and B atoms consisting of a long Al−C distance of 2.380(2) A and a B−C bond length of 1.681(3) A.
