Reactions of a series of bulky amidinate salts M[RC(NAr)2] (M = Li, Na or K; R = H, Fiso; Me, Aiso; But, Piso; Ar = 2, 6 - Pr2i C6 H3) with group 13 halides are reported. Treatment of the metal(I) halides, 'GaI' or InCl, with [Li(Fiso)] led to disproportionation reactions which gave the first gallium(II)-amidinate complex, [{GaI(Fiso)}2] (7), in addition to the metal(III) complexes, [GaI(Fiso)2] (8) and [InCl(Fiso)2] (10). Moreover, the Ga(II) compounds 7 and [{GaI(Piso)}2] (9) were synthesised in metathesis reactions between amidinate salts and [{GaI2(NHCy2)}2] (Cy=cyclohexyl). Treating [AlMe2(Aiso)], [{AlH2(Piso)}2] or [AlMe2(Piso)] with iodine in toluene led to isolation of the Al(III) iodide complexes [AlI2(Aiso)] (12), [AlI3(AisoH)] (13) and [AlI2(Piso)] (14). The adduct [GaCl3(FisoH)] (16) was obtained from the reactions of either [Na(Fiso)] or FisoH with GaCl3, whilst the amidinium salt [TripH2][InBr4] (17), (Trip = [TrC(NPri)2]-, Tr = 9-triptycenyl) was isolated from the reaction of [Li(Trip)] with InBr3. The X-ray crystal structures of 7, 9, 10, 13, 14, 16 and 17 are reported.
