Cyclopentadienyliron dicarbonyl dimer is an organometallic compound with the formula [ (η5 -C 5 H 5)Fe (CO) 2] 2, often abbreviated to Cp 2 Fe 2 (CO) 4, [CpFe (CO) 2] 2 or even Fp 2, with the colloquial name "fip dimer". It is a dark reddish-purple crystalline solid, which is readily soluble in moderately polar organic solvents such as ...
Iron (II) cyanide. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Iron (II) cyanide is an inorganic compound with the empirical formula Fe (CN) 2. It may have a Fe 2 [Fe (CN) 6] structure. [1][better source needed]
Iron (II) chloride tetrahydrate, FeCl2·4H2O. In chemistry, iron (II) refers to the element iron in its +2 oxidation state. The adjective ferrous or the prefix ferro- is often used to specify such compounds, as in ferrous chloride for iron (II) chloride (FeCl2). The adjective ferric is used instead for iron (III) salts, containing the cation Fe 3+.
F.E.1, Vickers VIM. Between 1911 and 1914, the Royal Aircraft Factory used the F.E.2 ("Farman Experimental 2") designation for three quite different aircraft that shared only a common "Farman" pusher biplane layout. The third "F.E.2" type was operated as a day and night bomber and fighter by the Royal Flying Corps during the First World War.
Metal nitrosyl complex. Sodium nitroprusside, a medicinally significant metal nitrosyl-pentacyanoferrate (Fe-III) compound, used to treat hypertension. [1] Metal nitrosyl complexes are complexes that contain nitric oxide, NO, bonded to a transition metal. [2] Many kinds of nitrosyl complexes are known, which vary both in structure and co ligand.
Iron is a chemical element; it has the symbol Fe (from Latin ferrum 'iron') and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core.
Iron (II) acetate describes compounds with formula Fe (CH3CO2)2· (H2O)x where x can be 0 (anhydrous) or 4 (tetrahydrate). The anhydrous compound is a white solid, although impure samples can be slightly colored. [1] The tetrahydrate is light green solid that is highly soluble in water.
There are 28 known radioactive isotopes and 8 nuclear isomers, the most stable of which are 60 Fe (half-life 2.6 million years) and 55 Fe (half-life 2.7 years). Much of the past work on measuring the isotopic composition of iron has centered on determining 60 Fe variations due to processes accompanying nucleosynthesis (i.e., meteorite studies ...
