Syntheses and reactions of tetrazole-group 13 complexes
摘要:
The combination of 5-phenyl-1-H-tetrazole (tet) with AIR(3) in stoichiometries of 1-3 leads to the compounds [(tet)AIR(2)](n) R = Me (1), Et (2),Bu-i (3), [(tet)(2)AlMe](n) (4), and [(tet)(3)Al](n) (5). The addition of pyridine to 1 leads to a soluble compound with the formulation, [(tet)AlMe2-pyridine](n) (6). Likewise the addition of AlMe3 to 1 and 4 leads to the products [(tet)AlMe2-AlMe3](2) (7) and [(tet)(2)AlMe-AlMe3](n) (8). The compounds were characterized by standard techniques and, in the case of 7 by X-ray crystallography. Compounds 1, 4 and 5 were examined (unsuccessfully) as potential unimolecular precursors to aluminum nitride. (C) 1998 Elsevier Science Ltd. All rights reserved.
