Sulphonic acids RSO3H (R=CH3, CF3, or C6H4CH3-p) react with the precursors (M=Ru or Os) and or in refluxing benzene or toluene to afford the complexes and respectively.The precursors and react with sulphonic acids in refluxing benzene to give the η6-benzene complexes 6-C6H6)(PPh3)2>.However a similar reaction in refluxing ethanol yielded .The complexes have been shown by variable-temperature 1H and 31P-<1H> n.m.r. spectroscopy to be fluxional in solution.The solid-state structure of one example, has been determined by X-ray diffraction methods.The crystals are monoclinic, space group P21/n, with a=24.382(5), b=18.075(4), c=10.729(2) Angstroem, β=99.03(2) grad, and Z=4.The octahedral ruthenium(II) complex contains monodentate sulphonate ligands (trans to PPh3 and CO) and an aqua ligand (trans to PPh3) with strong hydrogen-bonding interactions between the H atoms of the H2O and the non-co-ordinated oxygen atoms of the sulphonate ligands.The molecular structure is very similar to that previously reported for the alcohol dehydrogenation catalyst .
