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.
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]
Similar to the prokaryotic nitrate reduction mechanism, in eukaryotic nitrate reductase, an oxygen in nitrate binds to Mo in the (IV) oxidation state, displacing a hydroxide ion. Then the Mo d-orbital electrons flip over, creating a multiple bond between Mo(VI) and that oxygen, ejecting nitrite.
Molybdenum deficiency symptoms in most plants are associated with a build-up of nitrate in the affected plant part. This is a result of poor nitrate reductase activity. Symptoms include: [1] [2] pale leaves with interveinal and marginal chlorosis (yellowing) and necrosis (scald); the whiptail disorder in Brassica crops (especially cauliflower);
A transition metal nitrate complex is a coordination compound containing one or more nitrate ligands. Such complexes are common starting reagents for the preparation of other compounds. Such complexes are common starting reagents for the preparation of other compounds.
Hexagonal boron nitride, which adopts a layered structure, is a useful high-temperature lubricant akin to molybdenum disulfide. Nitride compounds often have large band gaps, thus nitrides are usually insulators or wide-bandgap semiconductors; examples include boron nitride and silicon nitride.
