Molybdenum is a chemical element; it has symbol Mo (from Neo-Latin molybdaenum) and atomic number 42. The name derived from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. [12]
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.
Molybdenum nitride (Mo 2 N) is a binary inorganic compound composed of molybdenum and nitrogen. It belongs to the family of transition metal nitrides and exhibits properties that make it useful in applications such as a catalyst and a coating material.
Ammonium heptamolybdate is the inorganic compound whose chemical formula is (NH 4) 6 Mo 7 O 24, normally encountered as the tetrahydrate.A dihydrate is also known. It is a colorless solid, often referred to as ammonium paramolybdate or simply as ammonium molybdate, although "ammonium molybdate" can also refer to ammonium orthomolybdate, (NH 4) 2 MoO 4, and several other compounds.
The first synthetic route to Mo(N 2) 2 (DPPE) 2 involved a reduction of molybdenum(III) acetylacetonate with triethylaluminium in the presence of dppe and nitrogen. A higher yielding synthesis involves a four-step process. [4] In the first step, molybdenum(V) chloride is reduced by acetonitrile (CH 3 CN) to give [MoCl 4 (CH 3 CN) 2].
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
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 hexacarbonyl (also called molybdenum carbonyl) is the chemical compound with the formula Mo(CO) 6. This colorless solid, like its chromium , tungsten , and seaborgium analogues, is noteworthy as a volatile, air-stable derivative of a metal in its zero oxidation state.
