Crystal structure. cubic. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Cobalt (III) nitrate is an inorganic compound with the chemical formula Co (NO 3) 3. [1] It is a green, diamagnetic solid that sublimes at ambient temperature. [2]
Pentaamminenitritocobalt (III) chloride is an inorganic compound with the molecular formula [Co (NH 3) 5 (NO 2)]Cl 2. It is an orange solid that is soluble in water. Although it has no applications, the compound has been of academic interest as a source of the transition metal nitrite complex [Co (NH 3) 5 (NO 2)] 2+.
Cobalt can easily react with nitric acid to form cobalt(II) nitrate Co(NO 3) 2. Cobalt(II) nitrate exists in the anhydrous form and the hydrate form, of which the hexahydrate is the most common. Cobalt nitrate hexahydrate (Co(NO 3) 2 ·6H 2 O) is a red deliquescence crystal that is easily soluble in water, [12] and its molecule contains cobalt ...
Sodium hexanitritocobaltate (III) is inorganic compound with the formula Na3[Co (NO2)6]. The anion of this yellow-coloured salt consists of the transition metal nitrite complex [Co (NO2)6]3−. It was a reagent for the qualitative test for potassium and ammonium ions. [ 2 ]
Infobox references. Chloropentamminecobalt chloride is the dichloride salt of the coordination complex [Co (NH 3) 5 Cl] 2+. It is a red-violet, diamagnetic, water-soluble salt. The compound has been of academic and historical interest.
Infobox references. cis-Dichlorobis (ethylenediamine)cobalt (III) chloride is a salt with the formula [CoCl 2 (en) 2]Cl (en = ethylenediamine). The salt consists of a cationic coordination complex and a chloride anion. It is a violet diamagnetic solid that is soluble in water. One chloride ion in this salt readily undergoes ion exchange, but ...
Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal.
