Abstract

The reaction of Lewis bases L with [{MF2(CO)(3)}(4)] (M=Ru or Os) in organic solvents provided a clean, high-yield, route to a series of air-and moisture-stable ruthenium(II) and osmium(II) fluoride co-ordination compounds of general formulae [MF2(CO)(2)L-2]. Characterisation by elemental analysis, FAB mass spectrometry, NMR and IR spectroscopy indicated a cis,cis,trans ligand arrangement. The crystal structures of [OC-6-13][MF2(CO)(2)(PR3)(2)] [M=Ru, PR3=PEtPh2; M=Os, PR3=PPh3 or P(C6H11)(3)] have been determined by X-ray crystallography. The geometry about the central metal atoms for all three structures is distorted pseudooctahedral with ligand environments consistent with the spectroscopic data. In all the structures the phosphine ligands are bent towards the fluoride ligands and show intramolecular H ... F interactions.
