Tungsten hexacarbonyl properties

Tungsten hexacarbonyl is a achromatic and odorless airy solid. The body of 2.65g/cm3. The temperature of 169～ 170 ℃. Sublimation temperature 50 ℃. Acrid in ether, 2- methoxy ethyl ether, and hexane. Rise of vacuum. Can be fabricated of tungsten crumb and carbon monoxide beneath top temperature and top burden system, or by six tungsten chloride and carbon monoxide in the ether, zinc or aluminum as the abbreviation abettor is able by reductive carbonylation reaction, can aswell use six tungsten chloride and six carbonyl adamant in ethyl ether, top burden hydrogen acknowledgment altitude can aswell be able in six chloride tungsten and azure in benzene at 50 ℃, 7000kPa canyon into the acknowledgment of carbon monoxide, butane ( C4H10 ) is off. For the alertness of top authentic tungsten powder, catalyst, amoebic synthesis. The baptize is usually hardly deleterious, don't administer undiluted or ample acknowledgment to groundwater, baptize or carrion system, after the permission of the government not the actual is absolved into the surrounding environment.

Tungsten hexacarbonyl is able by the abridgement of WCl6 beneath a burden of carbon monoxide. It would be attenuate to adapt this bargain admixture in the class because the accoutrement is big-ticket and the admixture can be purchased cheaply. The admixture is almost air-stable. It is sparingly acrid in nonpolar amoebic solvents. Tungsten carbonyl is broadly acclimated in electron beam-induced degradation address - it is calmly vaporized and addle by the electron axle accouterment a acceptable antecedent of tungsten atoms.W ( CO ) 6 adopts an octahedral geometry consisting of six rod-like CO ligands beaming from the axial W atom with dipole moment 0 D.This achromatic compound, like its chromium and molybdenum analogs, is noteworthy as a volatile, air-stable acquired of tungsten in its aught blaze state.
