Cobalt(II) azide (Co(N 3) 2) is another binary compound of cobalt and nitrogen that can explode when heated. Cobalt(II) and azide can form Co(N 3) 2− 4 complexes. [9] Cobalt pentazolide Co(N 5) 2 was discovered in 2017, and it exists in the form of the hydrate [Co(H 2 O) 4 (N 5) 2]·4H 2 O. It decomposes at 50~145 °C to form cobalt(II) azide ...
Its name stems from the contained element cobalt, whose name is attributed to the German term Kobold, referring to an "underground spirit" or "goblin". The notion of "bewitched" minerals stems from cobaltite and other cobalt ores withstanding the smelting methods of the medieval period, often producing foul-smelling, poisonous fumes in the process.
Cobalt(II) oxalate is the inorganic compound with the formula of CoC 2 O 4. Like other simple inorganic oxalates, it is a coordination polymer. The oxalate ligands bridge of Co(OH 2) 2 centres. Each cobalt adopts octahedral coordination geometry. [1] It is used in the preparation of cobalt catalysts, and cobalt metal powder for powder ...
Cobalt(III) oxide is the inorganic compound with the formula of Co 2 O 3. Although only two oxides of cobalt are well characterized, CoO and Co 3 O 4, [4] procedures claiming to give Co 2 O 3 have been described. Thus treatment of Co(II) salts such as cobalt(II) sulfate with an aqueous solution of sodium hypochlorite (also known as bleach ...
Cobalt sulfide is the name for chemical compounds with a formula Co x S y. Well-characterized species include minerals with the formulas CoS, CoS 2 , Co 3 S 4 , and Co 9 S 8 . In general, the sulfides of cobalt are black, semiconducting , insoluble in water, and nonstoichiometric .
