The alane complexes (C5H7N2R2)AlH2 (2) (R= Me,Pr-i, Ph) are obtained from the vinamidines C5H8N2R2 (1) and Me3N . AlH3 as reactive solids in good yields. Excess hydride reagent affords the formation of perhydrogenated ring systems from which (C11H24N2)Al2H4}(2) (6) could be prepared in a preparative scale. The X-ray structures of (C5H7N2Me2)AlH2 (2a) and ((C5H7N2Pr2)-Pr-i)AlH2 (2b) exhibit the expected near planar ring geometries. In 6. two units of (C11H2SN2)Al2H4 (5) are connected via hydrogen bridges to form a central planar Al2H2 core.
