The reaction of the trialkyl metals (R3M, R = Me, Et; M = Ga, In) with benzo[h]quinolin-10-ol (HO-BQ) in a 1:1 molar ratio gave intramolecular N coordinated complexes R2M-O-BQ (M = Ga, R = Me 1, Et 2) and (R2In-O-BQ)(...The reaction of the trialkyl metals (R3M, R = Me, Et; M = Ga, In) with benzo[h]quinolin-10-ol (HO-BQ) in a 1:1 molar ratio gave intramolecular N coordinated complexes R2M-O-BQ (M = Ga, R = Me 1, Et 2) and (R2In-O-BQ)(2) (M = In, R = Et 3,) in 80-90% yield. The molecular structures of complexes 1 and 3 have been established by X-ray crystallography.展开更多
