(R,RFc,SRu)-Chlorido(η6-p-cymene){1-[1-(diphenylphosphanyl)ethyl]-2-[2-(diphenylphosphanyl)phenyl]ferrocene-κ2P,P′}ruthenium(II) hexafluoridophosphate
Abstract
The asymmetric unit of the title compound, [FeRuCl(C5H5)(C10H14)(C37H31P2)]PF6, contains two independent, geometrically similar RuII complexes of a chiral ferrocenyldiphosphane with piano-stool coordination through the η6-bound p-cymene ligand, two chelating phosphorus donor atoms, and an exo-oriented chloride ion. The mean bond lengths of the two Ru complexes are Ru—C = 2.276 Å, Ru—P = 2.3816 Å, and Ru—Cl = 2.3924 Å. Both chloride ligands form only intramolecular C—H...Cl interactions. Seven weak intermolecular C—H...F interactions involving mainly arene H atoms consolidate the crystal packing, which reveals an approximate c/2 pseudo-translation relating the two independent Ru complex molecules.
