Abstract

The novel hydride-bridged tetranuclear aluminum complex {AlH₂[C₄H₂N(CH₂ NMe₂)₂-2,5]AlH₃}₂ (2) and the related deuterium complex {AlD₂[C₄H₂N(CH₂ NMe₂)₂-2,5]AlD₃}₂ (2-D) have been synthesized by reaction of AlCl₂[C₄H₂N(CH₂ NMe₂)₂-2,5] (1) with 2 equiv of LiAlH₄ or LiAlD₄. The crystal structure of complex 2-D reveals an unusual structure in which the aluminum atoms are in a square-planar arrangement. Reaction of 2 with 2 equiv of H₂O in diethyl ether affords the aluminum dihydride complex [C₄H₂N(CH₂NMe₂)₂-2,5] AlH₂ (3).
