The reaction of Lewis bases L with [{MF2(CO)3}4] (M 4;= 4;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)2L2]. 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 4;= 4;Ru, PR3 4;= 4;PEtPh2; M 4;= 4;Os, PR3 4;= 4;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 pseudo-octahedral 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 4;· 4;· 4;· 4;F interactions. |
