Abstract

The heptanuclear aluminium-nitrogen cage compound [(AlMe2)4(AlMe)3(NHNMe)3(N-NMe)(OMe)] contains the unique hydrazinetriide fragment [N-N(Me)]3- stabilized by coordination to five Al atoms. It was synthesised by thermolysis of the sesqui-hydrazide Al[(μ-NH-NHMe)2AlMe2]3 in refluxing toluene in the presence of a small quantity of methanol.
