摘要：

The aluminum and gallium dimethyl complexes, [Bp(But,Me)]AlMe2 and [Bp(But,Me)]GaMe2, are readily obtained by the reactions of [Bp(But,Me)]Tl with Me3Al and Me3Ga, respectively. [Bp(But,Me)]AlMe2 and [Bp(But,Me)]GaMe2 have been structurally characterized by X-ray diffraction, which indicates that the most noticeable difference in these otherwise very similar structures is the C-M-C bond angle, which increases from 118.9(3)degrees for [Bp(But,Me)]AlMe2 to 124.0(2)degrees for [Bp(But,Me)]GaMe2.
