Cyclopentadienyltungsten tricarbonyl dimer ((C 5 H 5.) 2 W 2 (CO) 6) is produced from W(CO) 6. Treatment of tungsten hexacarbonyl with sodium cyclopentadienide followed by oxidation of the resulting NaW(CO) 3 (C 5 H 5) gives cyclopentadienyltungsten tricarbonyl dimer. [5] One derivative is the dihydrogen complex W(CO) 3 [P(C 6 H 11) 3] 2 (H 2). [2]

WF 6 + 3 H 2 → W + 6 HF. The crystallinity of the produced tungsten layers can be controlled by altering the WF 6 / H 2 ratio and the substrate temperature: low ratios and temperatures result in (100) oriented tungsten crystallites whereas higher values favor the (111) orientation. Formation of HF is a drawback, as the HF vapor is very ...

Hexamethyltungsten is the chemical compound W(CH 3) 6 also written WMe 6.Classified as a transition metal alkyl complex, hexamethyltungsten is an air-sensitive, red, crystalline solid at room temperature; however, it is extremely volatile and sublimes at −30 °C.
