Abstract
Ethereal solvents to precipitate [ruthenium (arene) (phosphorus ligand) (halogen)] complexes result in complexes having reduced stability. The stability of [ruthenium (arene) (phosphorus ligand) (halogen)] complexes is improved when the complexes are triturated or precipitated with at least one alkane. The at least one alkane can be pentane isomers, hexane isomers, heptane isomers, octane isomers and combinations thereof.
