As a consequence of its structure where there are no significant lattice forces, gallium trichloride has the lowest melting point of all of the aluminium, gallium and indium trihalides. The formula of Ga 2 Cl 6 is often written as Ga 2 (Î¼-Cl) 2 Cl 4.
Gallium trichloride is formed by the reaction of gallium metal with chlorine gas. Unlike the trifluoride, gallium(III) chloride exists as dimeric molecules, Ga 2Cl 6, with a melting point of 78 Â°C. This is also the case for the bromide and iodide, Ga 2Br 6 and Ga 2I 6.
