Tungsten hexacarbonyl (also called tungsten carbonyl) is an organometallic compound with the formula W(CO) 6. This complex gave rise to the first example of a dihydrogen complex. [2] Like its chromium and molybdenum analogs, this colorless compound is noteworthy as a volatile, air-stable derivative of tungsten in its zero oxidation state.
Values are given in terms of temperature necessary to reach the specified pressure. Valid results within the quoted ranges from most equations are included in the table for comparison. A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875).
