The reaction of InCl3 with 1,3-diphenyltriazene (Hdpt) in the presence of NEt3 gives the six-co-ordinate indium complex 1a.The interaction of 1a with Cl and Cl allows for the isolation of the appropriate salts, 1b and 1c.Reaction of Lewis bases, L, with 1a yields , L = pyridine 2, 3,5-dimethylpyridine 3, PEt3 4, L2 = 2,2'-bipyridine 5, 1,10-phenanthroline 6, Me2PCH2CH2PMe2 7 or Et2PCH2CH2PEt2 8.The mechanism for these reactions is discussed.No rection is observed between 1b and 3,5-dimethylpyridine.The X-ray structures of 1a, 3, 4 and 5 have been determined.Compounds 2-4 are readily soluble in aromatic hydrocarbon solvents, while 5-8 are insoluble as a consequence of the presence of a supramolecular architecture involving dipolar In-Cl---N interactions in the solid state.All new compounds have been characterised by ¹H, ¹³C-<¹H> and ³¹P-<¹H> NMR and IR spectroscopy.
