Many molybdenum oxides are used as heterogeneous catalysts, e.g. for oxidations. Molybdic acid and its salts are used to make the Froehde reagent for the presumptive identification of alkaloids. References
Molybdenum is a chemical element; it has symbol Mo (from Neo-Latin molybdaenum) and atomic number 42. The name derived from Ancient Greek ...
Molybdenum(II) acetate is a coordination compound with the formula Mo 2 (O 2 CCH 3) 4. It is a yellow, diamagnetic , air-stable solid that is slightly soluble in organic solvents. Molybdenum(II) acetate is an iconic example of a compound with a metal-metal quadruple bond .
Molybdenum is an essential element in most organisms; a 2008 research paper speculated that a scarcity of molybdenum in the Earth's early oceans may have strongly influenced the evolution of eukaryotic life (which includes all plants and animals). [1] At least 50 molybdenum-containing enzymes have been identified, mostly in bacteria.
Molybdenum nitride can be synthesized through various methods, [2] [3] including: Direct nitridation: Molybdenum metal can react with nitrogen gas at elevated temperatures to form Mo 2 N. Ammonolysis : Molybdenum precursors, such as molybdenum oxides or molybdates, can be treated with ammonia gas or ammonia-containing solutions to produce ...
Fosdenopterin was approved for medical use in the United States in February 2021, [4] It is the first medication approved by the U.S. Food and Drug Administration (FDA) for the treatment of molybdenum cofactor deficiency type A. [2] and in the European Union in September 2022. [3]
It can also be prepared from the reduction of molybdenum(IV) bromide with molybdenum metal, hydrogen gas, or a hydrocarbon. [2] It has a structure consisting of infinite chains of face-sharing octahedra with alternatingly short and long Mo-Mo contacts. The same structure is adopted by the tribromides of ruthenium and technetium.
The metal atoms are usually group 6 (Mo, W) or less commonly group 5 (V, Nb, Ta) transition metals in their highest oxidation states. They are usually colorless to orange, diamagnetic anions. For most heteropolymetalates the W, Mo, or V, is complemented by main group oxyanions phosphate and silicate. Many exceptions to these general statements ...
