    FeCl 3 + 3 CH 3 CH 2 ONa → "Fe(OCH 2 CH 3) 3" + 3 NaCl Iron(III) chloride forms a 1:2 adduct with Lewis bases such as triphenylphosphine oxide ; e.g., FeCl 3 (OP(C 6 H 5 ) 3 ) 2 . The related 1:2 complex FeCl 3 (OEt 2 ) 2 , where Et = C 2 H 5 ) , has been crystallized from ether solution.

  3. Ferric - Wikipedia

    en.wikipedia.org/wiki/Ferric

    Potassium ferrioxalate contains the iron(III) complex [Fe(C 2 O 4) 3] 3−. In chemistry, iron(III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron(III) chloride (FeCl 3). The adjective ferrous is used instead for iron(II) salts, containing the cation Fe 2+.

    This reaction gives the methanol solvate of the dichloride, which upon heating in a vacuum at about 160 °C converts to anhydrous FeCl 2. [4] The net reaction is shown: Fe + 2 HCl → FeCl 2 + H 2. FeBr 2 and FeI 2 can be prepared analogously. An alternative synthesis of anhydrous ferrous chloride is the reduction of FeCl 3 with chlorobenzene: [5]

  6. Tetrachloroferrate - Wikipedia

    en.wikipedia.org/wiki/Tetrachloroferrate

    Tetrachloroferrate is the polyatomic ion having chemical formula FeCl − 4. The metallate can be formed when ferric chloride (FeCl 3) abstracts a chloride ion from various other chloride salts. [1] The resulting tetrachloroferrate salts are typically soluble in non-polar solvents.

  7. Iron (III) oxide-hydroxide - Wikipedia

    3 + 3 NaNO 3. In fact, when dissolved in water, pure FeCl 3 will hydrolyze to some extent, yielding the oxyhydroxide and making the solution acidic: [12] FeCl 3 + 2 H 2 O ↔ FeOOH + 3 HCl. Therefore, the compound can also be obtained by the decomposition of acidic solutions of iron(III) chloride held near the boiling point for days or weeks ...

  8. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    Most compounds considered to be Lewis acids require an activation step prior to formation of the adduct with the Lewis base. Complex compounds such as Et 3 Al 2 Cl 3 and AlCl 3 are treated as trigonal planar Lewis acids but exist as aggregates and polymers that must be degraded by the Lewis base. [10] A simpler case is the formation of adducts ...

    FeOCl is prepared by heating iron(III) oxide with ferric chloride at 370 °C (698 °F) over the course of several days: [2]. Fe 2 O 3 + FeCl 33 FeOCl. Alternatively, FeOCl may be prepared by the thermal decomposition of FeCl 3 ⋅6H 2 O at 220 °C (428 °F) over the course of one hour: [3]
