9‐Gallafluorenes were synthesized from 9‐zincafluorene·tmeda as an alternative to 2,2′‐biphenylenmercury and 2,2′‐dilithiobiphenyl. The zincafluorene was found to be only one possible form of a biphenylene zinc. In dependence of the synthetic conditions a dimeric zinc bridged structure resulted, too. The gallafluorenes obtained were stabilized by nitrogen donors or formed dimers in case of 9‐tert‐butoxygallafluorene

Alkyl- and phenylbis(dimethylamido)gallium, [RGa(NMe2)(2)](2) [R = Me (1), Et (2), Bu-n (3), (n)Hx (4), and Ph (5)], were synthesized by reactions of LiNMe2 with (RGaCl2)(2). The crystal structure of compound 1 was a disordered mixture of anti and syn isomers, with the ratio of anti/syn being 64:36, which was consistent with the ratio (57:43) found in the H-1 NMR spectrum. The Ga2N2 cores of the anti and syn structures were nonplanar. H-1 NMR spectra indicated the presence of both anti and syn isomers for all of the other substituents. H-1 NMR and mass spectra indicated that a species with the general formula of R3Ga2(NMe2)(3) was formed when these compounds were heated at high temperatures.
