title: Synthesis and structures of aluminium monohydride and chalcogenides bearing a bidentate [N,O] ligand.
abstract: The aluminium monohydride (3-tBu-5-Me-2-(O)C(6)H(2)CH(2)-N-2,6-iPr(2)C(6)H(3))AlH(NMe(3))(2) was prepared by treatment of the bidentate salicylaldimine [3-tBu-5-Me-2-(OH)C(6)H(2)CH=N-2,6-iPr(2)C(6)H(3)](1) with a small excess of AlH(3).NMe(3) in high yield. Compound 2 reacted with sulfur and selenium respectively to afford the dimeric aluminium chalcogenide [(3-tBu-5-Me-2-(O)C(6)H(2)CH(2)-NH-2,6-iPr(2)C(6)H(3))Al(micro-E)](2)[E = S (3), E = Se (4)]. During the formation of 2 hydrogen migration from the aluminium centre to the ligand backbone occurred. A possible reaction mechanism for 3 and 4 is discussed and the molecular structures of compounds 2-4 were determined by X-ray structural analyses.
