Tungsten hexacarbonyl (also called tungsten carbonyl) is the chemical compound with the formula W(CO)6. This complex gave rise to the first example of a dihydrogen complex.
Additional recommended knowledge
Preparation, properties, and structure
W(CO)6 is prepared by the reduction of WCl6 under a pressure of carbon monoxide. It would be rare to prepare this inexpensive compound in the laboratory because the apparatus is expensive and the compound can be purchased cheaply. The compound is relatively air-stable. It is sparingly soluble in nonpolar organic solvents.
All reactions of W(CO)6 commence with displacement of some CO ligands in W(CO)6. W(CO)6 behaves similarly to the Mo(CO)6 but tends to form compounds that are kinetically more robust.
One derivative is the dihydrogen complex W(CO)3[P(C6H11)3]2(H2) reported in 1982 by Kubas.
Safety and handling
Like all metal carbonyls, W(CO)6 is dangerous source of volatile metal as well as CO.
