M(OTf)3(M = Al,Ga,In; OTf = CF 3SO 3-)与2,2 ′:6′,2 Mobi '-三联吡啶(terpy)在CH 2Cl 2中反应,而与2,2 ′-联吡啶(bipy)和1,10-邻菲咯啉(phen)反应,分离得到顺式-[M”(OTf)2(bipy)2]OTf(M”= Al,Ga),顺式-[In(OTf)(H2O)(bipy)2][OTf]2,顺式-[Al(OTf)2(phen)2][OTf]和[In(H2O)2(phen)2][OTf]3.同时还得到了mer-[In(OTf)_3(terpy)]、cis-[Ga(OTf)_2(bipy)_2][OTf]和顺式-[In(OTf)(H_2O)(bipy)_2][OTf]_2,沿着了少量副产物cis-[Ga(H_2O)_2(phen)_2][OTf]_3和氢氧桥二聚体[{In(terpy)(OTf)}_2(μ-OH)_2][OTf]_2的X射线结构,它们在金属离子上均为六配位。虽然无水配合物显示三氟甲磺酸根与金属离子的κ1-配位,但具有配位水(或氢氧化物)配体的那些物质显示水H原子与来自三氟甲磺酸根阴离子的O原子之间的显著H-键合相互作用。配合物经IR、1H、13 C {1H}、19 F {1H}和27 Al NMR谱和微量分析表征。19 F {1 H} NMR谱表明,在MeCN溶液中,配位的三氟甲磺酸酯被溶剂取代,但在真空中除去MeCN后,原始络合物似乎发生改革。
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.
