Ru(II) complexes containing chelating phosphine ligands. Synthesis, characterizatin, and x-ray crystal structures of dichlorobis (1,2-bis(diphenylphosphino)ethane)Ru(II) and the coordinatetively unsaturated trigonal-bipyramidal cation, chlorobis(1,2-bis(diphenylphosphino)ethane)Ru(II)

The reaction of trans-RuCl[sub 2](dppe)[sub 2] (1), with AgBF[sub 4] in tetrahydrofuran leads to abstraction of one of the halide ligands to produce the trigonal-bipyrimidal complex. [RuCl(dppe)[sub 2]]BF[sub 4] (2). Both products are characterized by [sup 31]P NMR spectroscopy and their crystal structures determined. For the coordinatively unsaturated trigonal-bipyramidal complex (2), the authors found no evidence for the presence of more than one species or fluxional behaviour at room temperature in the [sup 31]P NMR spectrum. This complex was found to possess a trigonal-bipyramidal geometry in the solid state. Crystals of 1 are monoclinic. Convergence to conventional R values of R = 0.043 and R[sub w] = 0.042 was obtained for 416 variable parameters and 2746 x = 87.52(2), [beta] = 72.7(0.2), [gamma] = 74.35(2) and V = 2529(1)[angstrom][sup 3]. Values of R = 0.072 and R[sub w] = 0.097 were obtained for 487 variable parameters and 3242 reflections with 1 > 3[sigma](1). Compound 2 is triclinic. 18 refs., 2 figs., 5 tabs.
