Bis(cyclopentadienyl)tungsten(IV) dichloride
Bis(cyclopentadienyl)tungsten(IV) dichloride (CAS 12184-26-8, C10H10Cl2W, molar mass 384.93 g/mol) is an organometallic tungstenocene complex, supplied by Tech Serve Solutions as a research-grade solid of 97% assay. Often written Cp2WCl2, it features a tungsten centre bonded to two cyclopentadienyl rings and two chloride ligands. It is used principally as a precursor in organometallic synthesis, catalysis research, materials science, and as a tungsten source for vapour-deposition chemistry.

Organometallic synthesis precursor
Serves as a versatile tungstenocene starting material for preparing other tungsten complexes. The reactive chloride ligands offer convenient sites for substitution and ligand-exchange chemistry.
Catalysis and inorganic chemistry research
Used in laboratory studies of tungsten coordination chemistry and catalysis. It supports investigations into metallocene reactivity and structure-activity relationships at the bench scale.
Vapour-deposition precursor chemistry
Of interest as a tungsten-bearing precursor within CVD and ALD precursor research for thin-film and materials work. Suitability for any specific deposition process should be confirmed by the user.
Materials science and micro/nanoelectronics studies
Applied in materials science and micro- and nano-electronics research where a defined molecular tungsten source is required. Typically handled at research and development scale.
