Group 13−Group 13 Donor−Acceptor Complexes

Group 13−group 13 donor−acceptor complexes Cp*M−Al(t-Bu)3 (M = Al 1, Ga 2, In 3) and Cp*M−Ga(t-Bu)3 (M = Al 4, Ga 5, In 6) were obtained from reactions between [Cp*M]x (M = Al, x = 4; Ga, In, x = 6) and M(t-Bu)3 (M = Al, Ga). 3, 4, and 6 represent the first compounds containing dative In(I)−Al(III), Al(I)−Ga(III), and In(I)−Ga(III) bonds. 1−6 were characterized by elemental analyses, mass and multinuclear NMR spectroscopy (1H, 13C), and single-crystal X-ray analysis (except for 5).
