Bis(2,4-dimethylpentadienyl)ruthenium(II)
Bis(2,4-dimethylpentadienyl)ruthenium(II) (CAS 85908-78-7; Ru(C7H11)2, RuC14H22, molar mass approximately 291.4 g/mol) is an organoruthenium complex in which the metal is bound by two open pentadienyl ligands. Supplied as a high-purity solid (assay 99%, melting point 91-93 degrees C), it serves chiefly as a volatile ruthenium source precursor for thin-film deposition and as a ruthenium reagent in catalysis and materials chemistry. Tech Serve Solutions supplies it for research and industrial use.

Ruthenium thin-film deposition precursor
Used as a volatile, soluble ruthenium source for atomic layer deposition (ALD) and chemical vapour deposition (CVD) of ruthenium and ruthenium-containing films. Its open pentadienyl ligands give favourable volatility and clean ligand removal.
Microelectronics and nanoelectronics
Applied in the fabrication of ruthenium metal layers, seed layers, diffusion barriers and electrode structures studied for advanced semiconductor and interconnect applications.
Catalysis and inorganic synthesis
Functions as a ruthenium source and organometallic building block in catalysis research and in the preparation of other ruthenium complexes and intermediates.
Materials science research
Employed as a solution-deposition and precursor reagent in the development of functional ruthenium-based coatings, nanostructures and supported materials.
