Bis(cyclopentadienyl)vanadium(II)
Bis(cyclopentadienyl)vanadium(II), commonly known as vanadocene, is an organometallic sandwich complex of vanadium with the formula V(C5H5)2 (CAS 1277-47-0) and a molecular weight of 181.13 g/mol. It is a moisture- and air-sensitive solid (melting point 165–167 °C) used chiefly as a vanadium source in chemical vapour deposition (CVD) and atomic layer deposition (ALD), and as a reagent in catalysis, inorganic synthesis and materials science. Tech Serve Solutions supplies it to research and industrial users worldwide.

CVD and ALD vanadium precursor
Vanadocene serves as a volatile, metal-organic vanadium source for chemical vapour deposition and atomic layer deposition. It is used to grow vanadium-containing thin films and coatings in materials science and micro/nanoelectronics.
Organometallic synthesis reagent
As a well-defined vanadium(II) metallocene, it is a useful building block in organometallic and inorganic synthesis. It enables access to a range of vanadium complexes and ligand-substituted derivatives.
Catalysis and inorganic chemistry
The compound is applied in catalysis and coordination studies where a low-valent, electron-rich vanadium centre is required. It supports investigations into reactivity, bonding and catalytic behaviour.
Materials and thin-film research
Vanadocene is employed in materials science programmes exploring vanadium oxides, nitrides and related functional films. Its defined stoichiometry makes it suitable for controlled deposition work.

What is Bis(cyclopentadienyl)vanadium(II) used for?
+
It is used mainly as a vanadium precursor for chemical vapour deposition (CVD) and atomic layer deposition (ALD) of vanadium-containing thin films, and as a reagent in catalysis, organometallic synthesis, inorganic chemistry and materials science. Also known as vanadocene, it provides a defined, volatile vanadium(II) source for research and industrial deposition work.
What is the CAS number and molecular formula of Bis(cyclopentadienyl)vanadium(II)?
+
The CAS number is 1277-47-0 and the molecular formula is V(C5H5)2, with a molecular weight of 181.13 g/mol. The MDL number is MFCD00058735. It is supplied as a solid with a melting point of 165–167 °C (literature).
What grade and purity does Tech Serve Solutions supply?
+
Tech Serve Solutions supplies Bis(cyclopentadienyl)vanadium(II) as a research- and industrial-grade material suitable for deposition, synthesis and laboratory use. We do not represent it as USP, BP or EP pharmacopoeia grade. Exact assay and packaging specifications are confirmed against the accompanying certificate of analysis on enquiry.
Is Bis(cyclopentadienyl)vanadium(II) hazardous, and how should it be handled?
+
Yes. It carries GHS pictograms GHS02 and GHS06 with the signal word Danger. The hazard statements are H228 (flammable solid), H301 (toxic if swallowed), H311 (toxic in contact with skin), H315 (skin irritation), H319 (serious eye irritation), H331 (toxic if inhaled) and H335 (may cause respiratory irritation). Handle it under inert, dry conditions with appropriate respiratory protection, gloves and eye/face protection, away from ignition sources, in accordance with the Safety Data Sheet.
How is Bis(cyclopentadienyl)vanadium(II) packed, shipped and exported?
+
Because it is air- and moisture-sensitive, it is packed in sealed, inert-atmosphere containers and is classified for transport as UN 2926, Class 4.1 (flammable solid), Packing Group III, with a German water hazard class WGK 3. Tech Serve Solutions exports globally with full documentation, hazard labelling and Safety Data Sheets; pack sizes and shipping mode are confirmed at the time of order.
