 Title    Benzylgallium-Verbindungen. Die Kristallstrukturen von [Mg3Br2  
 Abstract    ,4Cl1,6(OEt2)6][Ga(CH2Ph)4]2 • 0,5 Toluol und [(3,5-Me2C6H3CH2)2GaBr]2 Benzylgallium Compounds. The Crystal Structures of [Mg3Br2 4C1 j 6(OEt2)6][Ga(CH2Ph)4]2 • 0.5 Toluene and [(3,5-Me2C6H3CH2)2GaBr]2 [Mg3Br2 4C1] 6(OEt2)6][Ga(CH2Ph)4]2-0.5 toluene (1) can be obtained by the reaction of one equivalent of GaCl3 with four equivalents of PhCH2MgBr in Et20 . Recrystallization of the crude product from toluene at 60°C gives colorless crystals of 1. Treatment of GaCl3 with two equivalents 3,5-Me2C6H3CH2MgBr in Et20 gives after recrystallization from toluene the diorganogallium bromide [(3,5-Me2C6H3CH2)2GaBr]2 (2). 1 and 2 were characterized by NMR, IR and MS techniques as well as by X-ray structure analyses. 1 consists in the dication [Mg3Br2 4C1, 6(OEt2)6]2+, two gallate units [Ga(CH2Ph)4]_ and a toluene molecule, disordered around a center of inversion. 2 forms centrosymmetric dimers [(3,5-Me2C6H3CH2)2GaBr]2.
