The reaction of LiC CMe with [((Dip)nacnac)MgI(OEt(2))] ((Dip)nacnac = [(DipNCMe)(2)CH], Dip = 2,6-diisopropylphenyl) afforded [ ((Dip)nacnac)MgC CMe (2)] 1 in good yield. Treatment of 1 with AlH(3)center dot NMe(3) in toluene under reflux afforded a low yield of the novel imido aluminium magnesium hydride compound [ (AlH)(AlH(2))(3)(NDip)(3) (2)Mg] 2. The latter compound features a central Mg(2+) ion that is coordinated via hydride ligands to two monoanionic [(AlH)(AlH(2))(3)(NDip)(3)](-) fragments. The compounds have been characterised by (1)H and (13)C NMR spectroscopy, IR spectroscopy and the crystal structures of 1 and 2 center dot 4C(7)H(8) have been determined.
