“…Interestingly, the carboxylato ligand is, in terms of bond lengths, almost symmetrically bidentate to two different gallium units. For example, bond lengths Ga (1) [43][44][45][46]51]. Both gallium atoms, the four oxygen atoms and two carbon atoms of the two carboxylate fragments, form a puckered eight-membered ring.…”

“…These chelating ligands, stabilize gallium against hydrolysis, and therefore increase the anticancer activity. In spite of their chelating nature and stability, carboxylate gallium(III) complexes have not been studied in the context of medicinal chemistry and only structural properties regarding these compounds have been reported [41][42][43][44][45][46].…”

“…2-(hydroxyalkyl)pyridines, N-heterocyclic carboxylic acids, 2-(2-hydroxyphenyl)oxazoline and 1-(2-hydroxyethyl)pyrazoles (scheme 4), in 1:1 molar ratio in benzene afforded readily dimeric diorganometal complexes containing central rectangular 'M 2 (μ-O) 2 ' core (scheme 5). [20][21][22][23][24] The mass spectra showed peaks higher than the formula weight suggesting their associated nature. Gallium and indium species can be identified readily from the characteristic isotopic pairs ( 69 Ga/ 71 Ga; 113 In/ 115 In).…”

The chemistry of organo-gallium and indium complexes with dithiolate and internally functionalised oxo ligands has been explored. With 1,1-dithiolate ligands both classical and organometallic complexes of gallium and indium, [M(S ∩ S) 3 ], [RM(S ∩ S) 2 ] and [R 2 M(S ∩ S)] (where R = Me or Et; M = Ga or In; S ∩ S = RCS 2 , ROCS 2 , R 2 NCS 2 and (RO) 2 PS 2 ) have been isolated. Reactions of internally functionalised oxo ligands with R 3 M·OEt 2 afforded diorganometal complexes [R 2 ML] n . Molecular structures of several of these complexes have been established by single crystal X-ray diffraction analyses. Complexes derived from oxo ligands showed photoluminescence. They have been used as alkylating agents for C-C coupling reactions of aryl bromides in the presence of PdCl 2 (PPh 3 ) 2 . Indium dithiolate complexes have been used as molecular precursors for the preparation of mono dispersed β-In 2 S 3 nanoparticles.

Reactions of organomagnesium halides with group 13 metal halides lead to the formation of R3M type compounds (R = alkyl, aryl; M = Al, Ga, In) and are considered as the simplest methods of R3M compound syntheses. These seemingly simple reactions reveal a much more complex chemistry involving mixed magnesium‐group 13 metal compounds. To elucidate the reaction course of reactions of organomagnesium halides with group 13 metal halides, we have studied reactions of R3M with organomagnesium halides. The interaction of Et3M with R1MgX led to the formation of following products being mixtures of crystalline ionic complexes with the general composition of [Et4‐nR1nM]−[XMg (thf)5]+·(thf): [Et2.2Al(CH=CH2)1.8]−[BrMg (thf)5]+·(thf) (1), [Et3Ga(CH=CH2)]−[BrMg (thf)5]+·(thf) (2), [Et4Al]−[BrMg (thf)5]+·(thf) (3), [Et4Ga]−[BrMg (thf)5]+·(thf) (4), [Et2.9Al(C6H5)1.1]−[BrMg (thf)5]+·(thf) (5), [Et2.9Ga(C6H5)1.1]−[BrMg (thf)5]+·(thf) (6), [Et3.4GaMe0.6]−[IMg (thf)5]+·(thf) (7) and [Et4In]−[BrMg (thf)5]+·(thf) (8). A comparison of the production course of group 13 metal trialkyls R3M with a thermal decomposition of 1–8 products showed that reactions of MX3 with RMgX (X = Br, I; R = alkyl, aryl) yield initially intermediate ionic compounds, which must then be thermally decomposed to obtain pure R3M compounds. If group 13 metal bromides and iodides, and alkyl (aryl)magnesium bromides and iodides in thf are used, only intermediate products with the [R4M]−[XMg (thf)5]+·(thf) structure are formed.
