Gallium mesityl complexes

From solutions of GaCl2 in hot 1,3,5-trimethylbenzene the colorless crystalline bis(arene) complex [C6H3(CH3)3]2Ga+ GaCl4 (XLVI) has been isolated (158). The structural study reveals a bent sandwich structure for the cationic moiety, as indicated schematically in Fig. 9. The tetrachlorogallate tetrahedra are once more only weakly coordinated, this time via one chlorine atom each to the Ga(I) centers of two bis(arene)gallium units, forming a chainlike coordination polymer. The steric requirement of the mesityl ligands is... [Pg.247]

The reaction of phosphorus trichloride with tgrt-bufylamine was reported to give a dicoordinate phosph(III)azene Bu N=P-NHBu which can be deprotonated to the [Bu NPNBu ] anion. The crystal structure ofK[Bu NPNBu ] has been determined. The anion has also been found in a gallium and a lithium complex. In monomeric form, the [RN P NMes] anion can be obtained when R = mesityl (Mes = 2,4,6-Me3C6H2), tert-butyl and 1-adamantanyl, as dimeric lithium ring compounds (3) ... [Pg.3719]
