 Abstract    und Eigenschaften von Benzylgallium(indium)-Verbindungen. Die Kristallstrukturen von [(PhCH2)2GaBr]2, [(PhCH2)2GaN(H)f-Bu]2 und [PhCH2InCl2(THF)2] Synthesis and Properties o f Benzylgallium(indium) Compounds. The Crystal Structures o f [(PhCH2)2GaBr]2, [(PhCH2)2GaN(H)r-Bu]2 and [PhCH2InCl2(THF)2] (PhCH2)2GaBr (1) can be obtained by the redistribution reaction of GaBr3 with Ga(CH2Ph)3 in a molar ratio 1:2. Treatment of 1 or (PhCH2)2GaCl with one equivalent of LiN(H)/-Bu gives the diorganogallium amide [(PhCH2)2GaN(H)r-Bu]2 (2). The toluene-insoluble PhCH2InCl2 can be structurally investigated after dissolving in THF and crystallization as [PhCH2InCl2(THF)2] (3). 1 -3 were characterized with NMR, IR and MS techniques as well as by X-ray structure determinations. 1 forms two crystallographic independent dimers while 2 is a centrosymmetric dimer in the solid state. 3 is a monomer with a trigonal-bipyramidal coordination sphere at the indium center.

 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.

 Title    Organogallitimamide: Synthese und Kristallstrukturen von [IPr2GaN(H/Bu]2 und [Mes(Cl)GaN(H)'Bu]2 Organogallium Amides: Synthesis and Crystal Structures o f ['Pr-,GaN(H)'Bu]-, and [Mes(Cl)GaN(H)'Bu]2  
 Abstract    ['Pr2GaN(H)'Bu]2 (1) and [Mes(Cl)GaN(H)'Bu]2 (2) can be synthesized by the metathesis reaction of 'Pr2GaCl and MesGaCl2 with one equivalent of LiN(H)'Bu, respectively. 1 and 2 were characterized by NMR, IR and MS techniques as well as by X-ray structure analyses. 1 and 2 consist of centrosymmetric dimeric molecules with a G a2N2 skeleton. According to cryoscopic measurements in benzene, both amides
