  摘要：

  The reactions of (2,6-Mes(2)C(6)H(3))(2)GaCl (2) with LiMe, Li-t-Bu, and LiHBEt3 afforded the bis(terphenyl)gallium compounds (2,6-Mes(2)C(6)H(3))(2)GaMe (3), (2,6-Mes(2)C(6)H(3))(2)Ga-t-Bu (4) and (2,6-Mes(2)C(6)H(3))(2)GaH (5). Hydrolysis of 2 and 3 gave the dimeric, hydroxide-bridged species [2,6-Mes(2)C(6)H(3)Ga(Cl)(mu-OH)(2) (6) and [2,6-Mes(2)C(6)H(3)Ga(Me)(mu-OH)](2) (7) via loss of the terphenyl substituent as 1,3-Mes(2)C(6)H(4). Hydrolysis of 5 led to the loss of H-2 and the formation of the monomeric (2,6-Mes(2)C(6)H(3))(2)GaOH (8). The compounds were characterized by FTIR and H-1 and C-13{H-1} NMR spectroscopy and X-ray crystallography. The structural studies of the diterphenyl compounds 2-5 and 8 showed the highly flexible nature of these compounds, as expressed in the wide range of the C-Terph-Ga-C-Terph angles from 113.23degrees in 4 to 153.5degrees in 2. Methyl and hydride abstraction from 3 and 5 with the Lewis acids [Ph3C](+)[B(C6F5)(4)](-) and B(C6F5)(3) afforded the ionic species [(2,6-Mes(2)C(6)H(3))(2)Gal](+)[B(C6F5)(4)](-), [(2,6-Mes(2)C(6)H(3))(2-)Ga](+)[MeB(C6F5)(3)](-), and [(2,6-Mes(2)C(6)H(3))(2)Ga](+)[HB(C6F5)(3)](-), all of which contain the linear two-coordinate cation [(2,6-Mes(2)C(6)H(3))(2)Ga](+) (1(+)).
