Formation of a homoleptic unbridged metal–metal bonded isocyanide dimer of ruthenium(I) by metal–carbon bond cleavage in [Ru(1–2,5-η-C8H13)(CN-xylyl)4]PF6: the X-ray structure determination of [Ru2(CN-xylyl)10][BPh4]2
Abstract
Refluxing [Ru(1–2,5-η-C8H13)(CN-xylyl)4]PF6 in [2H6]acetone gives C8H13D and [Ru2(CN-xylyl)10][PF6]2; an X-ray structure determination of [Ru2(CN-xylyl)10][BPh4]2 shows the cation to be an unbridged, metal–metal bonded dimer of ruthenium(I) containing eclipsed 2,6-dimethylphenyl isocyanide ligands.
