Introduction	Tungsten carbonyl (molybdenum) complex is an important organometallic compound, which is formed by transition metal tungsten (molybdenum) and carbon monoxide ligand Coordination compounds, usually six ligands, are widely used in organic synthesis.
Application	Tungsten hexacarbonyl can be used as a catalyst, and can also be used for tungsten plating on metals or ceramics.
Preparation	Tungsten hexacarbonyl can be obtained by heating tungsten hexachloride, aluminum powder and carbon monoxide (1.1 × 107 Pa) to 100°C in a autoclave.
Use	Used to prepare tungsten-containing composites and materials, and also used in photochemistry.
