Abstract

The reactions of gallium subhalides Ga2X4·2dioxane (X = Cl, Br) and “GaI” with carbonylmetallates of chromium, iron and cobalt result in the formation of various gallium halide complexes. These are [(CO)5CrGaBr(thf)2] (6), with a terminal GaX unit, and [(CO)4FeGaCl(thf)]2 (1), [(CO)4FeGaCl2Na(thf)2]x (2), [(CO)4FeGaI2Na(thf)3]2 (4) and [Cr2(CO)8(GaI2)INa2(thf)7]x (8) with GaX units in the bridging positions of gallium-transition-metal rings. In addition, mixed cyclic gallium-iron hydroxides [(CO)4Fe2Ga4Cl5(OH)3(thf)] 3 and 4 and gallium oxo/hydroxo cages 5, 9 and 10 were observed. Rings of [GaCo4(CO)14K(thf)]6 (11), prepared from Ga4Cl4R4 [R = Si(SiMe3)3] and K[Co(CO)4], are connected through isocarbonyl-potassium interactions to form channels. All compounds were characterized spectroscopically and by X-ray crystallography. DFT calculations were performed on cobalt-gallium complexes to evaluate their bonding properties.
