The crystal structure of [ Ru ( terpy )( bpy )( pz )] (PF6)2 has been determined by X-ray diffraction methods and refined to a residual of 0.046 for 1855 independent observed reflections. The crystals are monoclinic, space group P 21/a, a 16.836(7), b 10.778(5), c l9.342(5) Ǻ, β 115.11(3)°. The coordination geometry around the ruthenium(II) ion is distorted octahedral, with the various Ru -N bond lengths indicative of considerable interligand steric strain. The Ru -N pyrazine bond is the longest within the structure, consistent with other evidence that n back-bonding to pyrazine is weak in the complex.
