Abstract

The reactions of anhydrous HF with the ruthenium(II) and osmium(II) hydride complexes [MH2(CO)(x)(PPh3)(y)] (M = Ru or Os; x = y = 2; x = 1, y = 3) have been studied. For [OC-6-13][MH2(CO)(2)(PPh3)(2)], elimination of dihydrogen affords the previously described [OC-6-13][MF2(CO)(2)(PPh3)(2)]. For [OC-6-13][MH2(CO)(PPh3)(3)], elimination of dihydrogen is accompanied by loss of one phosphine ligand and aggregation to give the novel, triply fluoride-bridged, dinuclear, [M-2(mu-F)(3)(CO)(2)(PPh3)(4)][HF2]; anion exchange with Na[BPh4] afford air-stable products These complexes have been characterised by mass spectrometry, NMR, IR and metal-edge extended X-ray absorption fine structure spectroscopies which confirm their dinuclear structures.
