[RuCl2 {PPh2 (2,6-Me2 C6 H3 )}2 ]: A Neutral 14-Electron Ruthenium(II) Complex with Two Agostic Interactions.

"Bidentate" ligand behavior is shown by (2,6-dimethylphenyl)diphenylphosphane in the title compound: In the nearly octahedral environment of the ruthenium atom two coordination sites are occupied by methyl groups of the two xylyl substituents. NMR investigation and an X-ray analysis (see picture) reveal that the methyl groups act as weak donors to form two strong agostic Ru⋅⋅⋅C-H interactions. © 1999 WILEY-VCH Verlag GmbH, Weinheim, Fed.
