The relatively insoluble "anthracenemagnesium" 1a*n THF reacts in THF with dialkylaluminium hydrides to give magnesium-μ-(9,10-dihydro-9,10-anthrylene)-dialkylhydridoaluminates 2a-c, with aluminium trihydride the corresponding -trihydridoaluminate 2d and with ethoxydiethylaluminium the -ethoxydiethylaluminate 6.The structures of the compounds 2a-c and 6 dissolved in THF were determined by NMR spectroscopy.An X-ray crystallographic investigation of 2b (alkyl = ethyl) shows that Al and Mg occupy axial positions in a 9,10-dihydro-9,10-anthrylene system.The Mg+ cation interacts with the hydride of the aluminate anion.Analogous complexes 3 with trialkylaluminium can only be obtained if 1a*n THF is reacted with (n+1) AlR3 (R = methyl, ethyl) in non-Lewis base solvents.Ether cause the cleavage of 3 into trialkylaluminium etherate, e.g. 4 or 5, and 1a, which is unstable in diethyl ether and decomposes into magnesium and anthracene.
