Iron(III) chloride has a relatively low melting point and boils at around 315 °C. The vapor consists of the dimer Fe 2 Cl 6 , much like aluminium chloride . This dimer dissociates into the monomeric FeCl 3 (with D 3h point group molecular symmetry ) at higher temperatures, in competition with its reversible decomposition to give iron(II ...
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.

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+.
Iron(III) oxide is insoluble in water but dissolves readily in strong acid, e.g., hydrochloric and sulfuric acids. It also dissolves well in solutions of chelating agents such as EDTA and oxalic acid. Heating iron(III) oxides with other metal oxides or carbonates yields materials known as ferrates (ferrate (III)): [18] ZnO + Fe 2 O 3 → Zn(FeO ...
Iron(III) oxyhydroxide precipitates from solutions of iron(III) salts at pH between 6.5 and 8. [12] Thus the oxyhydroxide can be obtained in the lab by reacting an iron(III) salt, such as ferric chloride or ferric nitrate, with sodium hydroxide: [13] FeCl 3 + 3 NaOH → Fe(OH) 3 + 3 NaCl Fe(NO 3) 3 + 3 NaOH → Fe(OH) 3 + 3 NaNO 3
Iron(III) stearate (ferric stearate) is a metal-organic compound, a salt of iron and stearic acid with the chemical formula Fe(C 17 H 35 COO)3. [2] [3] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid. [4]
Iron(II,III) oxide, or black iron oxide, is the chemical compound with formula Fe 3 O 4. It occurs in nature as the mineral magnetite . It is one of a number of iron oxides , the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2 O 3 ) which also occurs naturally as the mineral hematite .
