Аннотация

Monovalent gallanediyl LGa {L=HC[C(Me)N(2,6-iPr2C6H3)]2} reacts with SbX3 to form the Ga-substituted distibenes [(LGaX)2Sb2] (X=NMeEt 1, Cl 2). Upon heating, 2 reacts to the bicyclo[1.1.0]butane analogue [(LGaCl)2(μ,η1:1-Sb4)] 3 containing a [Sb4]2− dianion. Moreover, 2 reacts with Li amides LiNR2 in salt elimination reactions that form the corresponding amido-substituted compounds 1 and [(LGaNMe2)2Sb2] 4, whereas reactions of 4 and [(LGaNMe2)2(μ,η1:1-Sb4)] 5 with two equivalents of GaCl3 resulted in the formation of 2 and 3, respectively. 1, 2 and 3 were characterized by 1H and 13C NMR spectroscopy, elemental analysis, and single crystal X-ray diffraction. In addition, their bonding situation was analyzed by quantum chemical calculations.
