Infobox references. Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is MoS2. The compound is classified as a transition metal dichalcogenide. It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum. [6]
192.155 g/mol. Appearance. dark brown solid. Solubility in water. insoluble. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Molybdenum trisulfide is an inorganic compound with the formula MoS 3. [1]
Molybdenum(V) chloride MoCl 5 dark green solid, which adopts a dimeric structure. Molybdenum(VI) chloride MoCl 6 is a black solid, which is monomeric and slowly decomposes to MoCl 5 and Cl 2 at room temperature. [29] The accessibility of these oxidation states depends quite strongly on the halide counterion: although molybdenum(VI) fluoride is ...
Ammonium tetrathiomolybdate is the chemical compound with the formula (NH 4) 2 MoS 4. This bright red ammonium salt is an important reagent in the chemistry of molybdenum and has been used as a building block in bioinorganic chemistry. The thiometallate (see metallate) anion has the distinctive property of undergoing oxidation at the sulfur ...
3D model of the molybdate ion. In chemistry, a molybdate is a compound containing an oxyanion with molybdenum in its highest oxidation state of +6: O−−Mo (=O)2−O−. Molybdenum can form a very large range of such oxyanions, which can be discrete structures or polymeric extended structures, although the latter are only found in the solid ...
Molybdenum sulfide is a p-type material, but it shows ambipolar behavior when molybdenum sulfide monolayers that were 15 nm thick were used in transistors. [101] However, most electrical devices containing molybdenum sulfide monolayers tend to show n-type behavior. [97] [103]
Tungsten disulfide is an inorganic chemical compound composed of tungsten and sulfur with the chemical formula WS 2. This compound is part of the group of materials called the transition metal dichalcogenides. It occurs naturally as the rare mineral tungstenite. This material is a component of certain catalysts used for hydrodesulfurization and ...
Molybdenum trioxide is used to manufacture molybdenum metal: MoO 3 + 3 H 2 → Mo + 3 H 2 O. Molybdenum trioxide is also a component of the co-catalyst used in the industrial production of acrylonitrile by the oxidation of propene and ammonia. Because of its layered structure and the ease of the Mo (VI)/Mo (V) coupling, MoO 3 is of interest in ...
