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 ...
Structure of the FeMoco active site of nitrogenase The molybdenum cofactor (pictured) is composed of a molybdenum-free organic complex called molybdopterin, which has bound an oxidized molybdenum(VI) atom through adjacent sulfur (or occasionally selenium) atoms. Except for the ancient nitrogenases, all known Mo-using enzymes use this cofactor.
Molybdic acid refers to hydrated forms of molybdenum trioxide and related species. The monohydrate (MoO 3 ·H 2 O) and the dihydrate (MoO 3 ·2H 2 O) are well characterized. They are yellow diamagnetic solids.
Molybdenum oxide may refer to: Molybdenum(IV) oxide (molybdenum dioxide, MoO 2) Molybdenum(VI) oxide (molybdenum trioxide, MoO 3) Other stoichiometric binary molybdenum-oxygen compounds include Mo 8 O 23 [1] and Mo 17 O 47. [2]
Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is MoS 2. 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] MoS 2 is relatively unreactive.
The activity of xanthine oxidase is directly proportional to the amount of molybdenum in the body. An extremely high concentration of molybdenum reverses the trend and can inhibit purine catabolism and other processes. Molybdenum concentration also affects protein synthesis, metabolism, and growth. [10] Mo is a component in most nitrogenases ...
A trioxide is a compound with three oxygen atoms. For metals with the M 2 O 3 formula there are several common structures. Al 2 O 3 , Cr 2 O 3 , Fe 2 O 3 , and V 2 O 3 adopt the corundum structure .
ADM is an intermediate in the production of molybdenum compounds from its ores. Roasting typical ore produces crude molybdenum(VI) oxides, which can be extracted into aqueous ammonia, affording ammonium molybdate. Heating solutions of ammonium molybdate gives ADM. Upon heating, solid ammonium dimolybdate decomposes to molybdenum trioxide: [1]
