The reactions of M(OTf)3(M = Al, Ga, In; OTf = CF3SO3–) with 2,2′:6′,2′’- terpyridyl (terpy) in CH2Cl2gavemer-[M(OTf)3(terpy)], whilst with 2,2′-bipyridyl (bipy) and 1,10-phenanthroline (phen) the products isolated werecis-[M”(OTf)2(bipy)2]OTf (M” = Al, Ga),cis-[In(OTf)(H2O)(bipy)2][OTf]2,cis-[Al(OTf)2(phen)2][OTf] and [In(H2O)2(phen)2][OTf]3. The X-ray structures of mer-[In(OTf)3(terpy)],cis-[Ga(OTf)2(bipy)2][OTf] andcis-[In(OTf)(H2O)(bipy)2][OTf]2, along with those of the minor by-products,cis-[Ga(H2O)2(phen)2][OTf]3and the hydroxide-bridged dimer [{In(terpy)(OTf)}2(µ-OH)2][OTf]2were also obtained, all of which show six-coordination at the metal ion. While the anhydrous complexes show κ1-coordination of the triflate to the metal ion, those species with coordinated water (or hydroxide) ligands show significant H-bonding interactions between the water H atoms and the O-atoms from triflate anions. The complexes were characterised by IR,1H,13C{1H},19F{1H} and27Al NMR spectroscopy, together with microanalysis. The19F{1H} NMR spectra suggest that in MeCN solution the coordinated triflates are displaced by the solvent, but the original complexes appear to reform on removal of the MeCNin vacuo.
