The reactions of a variety of primary and secondary amines and secondary phosphanes with GaI have been examined. In all cases disproportionation reactions occurred which led to the gallium(II) iodide complexes [Ga2I4(L)2] [L = NCyH2, NtBuH2, NCy2H, PCy2H or PtBu2H (Cy = cyclohexyl)]. All complexes have been crystallographically characterised and have been shown to be dimers possessing Ga-Ga bonds. The reaction of the sterically hindered N-heterocyclic carbene IPr [:CN(Ar)C2H2N(Ar) (Ar = C6H3iPr2-2,6)] with GaI was also carried out and the novel salt [Ga2I5(IPr)][IPrH] was formed in good yield and crystallographically characterised. Finally, the related reaction of the less hindered cyclic carbene IMe [:CN(Me)C2Me2N(Me)] with InCl gave a low yield of the crystallographically characterised salt [{InCl(IMe)}2(μ-Cl)(μ-O)][Cl] which presumably forms due to the presence of adventitious oxygen in the reaction mixture.
