Tungsten hexacarbonyl Specification

Hexacarbonyltungsten (14040-11-0) is the chemical compound with the formula W(CO)₆. This complex gave rise to the first example of a dihydrogen complex.This colorless compound, like its chromium and molybdenum analogs, is noteworthy as a volatile, air-stable derivative of tungsten in its zero oxidation state.It 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. Tungsten carbonyl is widely used in electron beam-induced deposition technique - it is easily vaporized and decomposed by the electron beam providing a convenient source of tungsten atoms.
