Molar mass. 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.
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]
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 stable, molybdenum does not form a stable hexachloride, pentabromide, or ...
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 ...
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 ...
Molybdenum trioxide describes a family of inorganic compounds with the formula MoO 3 (H 2 O) n where n = 0, 1, 2. The anhydrous compound is produced on the largest scale of any molybdenum compound since it is the main intermediate produced when molybdenum ores are purified. The anhydrous oxide is a precursor to molybdenum metal, an important ...
The oxide ion has an ionic radius of 1.40 Å, molybdenum(VI) is much smaller, 0.59 Å. [1] There are strong similarities between the structures of the molybdates and the molybdenum oxides, ( MoO 3 , MoO 2 and the " crystallographic shear " oxides, Mo 9 O 26 and Mo 10 O 29 ) whose structures all contain close packed oxide ions.
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Sulfide (also sulphide in British English ) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive.
