Abstract
The piperidinyl-substituted aluminium azide, [(pip)2AlN3]2 (5) (pip = piperidinyl, N(CH2)4CH2), has been synthesised via the reaction between [(pip)2AlCl]2 and one equivalent of NaN3. A related pyrrolyl derivative, [(Me2N(H))Al(pyr)3] (7) (pyr = pyrrolyl, N(CH)3CH), was prepared via the dimethylamine elimination reaction between [Al2(NMe2)6] and six equivalents of pyrrole. A third aluminium amido complex, [Li(Al(NHtBu)4)]2 (9), has been isolated from the salt elimination reaction between AlCl3 and an excess of LiNHtBu. all three compounds have been characterised by X-ray crystallography; compounds 5 and 9 are dimeric in the solid state, whereas 7 is monomeric. © 1998 Elsevier Science Ltd.
