In the attempt to prepare the tris(cyclometalated) ruthenium derivative of 2‐phenylpyridine, [Ru(η 6 ‐C 6 H 6 )(phpy)Cl] was treated with Hg(phpy) 2 . The anticipated [Ru(phpy) 3 ] n + species was not formed. Instead, the product of oxidative coupling of two 2‐(2‐pyridinyl)phenyl ligands to form octahedral [Ru II (phpy)(pbp)]PF 6 with pbp = 2,2′‐bis(2‐pyridinyl)‐1,1′‐biphenyl was isolated; pbp forms a nine‐membered chelate with two N and two η 2 ‐C=C donor centers. The binding of η 2 ‐C=C donor units is weak as they are readily replaced by CO. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
