Tetrahydrofuran adducts of haloaluminum hydrides, A1HyX3-y.zTHF X C1, Br, I, and some deuterated analogs were prepared and characterized. The adducts are crystalline solids which are normally isolated as stoichiometric ditetrahydrofuranates. Cryoscopic and ebullioscopic molecular weight determinations in benzene and THF, respectively, indicate the compounds are monomeric in these solvents. Active hydrogen determinations indicate no initial cleavage of THF. X-Ray powder diffraction patterns indicate that A1H2C1.2THF, A1HC12.2THF, A1D2C1.2THF, A1DC12.2THF, A1H2Br.2THF, and A1HC1Br.2THF are isomorphous. Infrared frequencies for the A1-H and A1-D bands are reported and their relationship to the structure of the complexes is discussed. Proton magnetic resonance data confirm THF complex formulation.
