Abstract
During the disproportionation of metastable AlX-solutions (X = Cl, Br, I) donor-stabilized aluminiumdihalides are formed. X-ray diffraction analysis shows that all of them exhibit a dimeric structure DoX(2)Al-A lX(2)Do (Do = donor-molecule). The Al-Al-bond length which is signific antly shorter than in the organometallic R2Al-AlR2-species is strongly influenced by the donor-molecule as well as by the halogen ligands. W ith the help of quantum chemical calculations a deeper understanding o f this bonding situation is obtained.
