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.
Boca Raton, Florida, 2003; Section 6, Fluid Properties; Critical Constants. Also agrees with Celsius values from Section 4: Properties of the Elements and Inorganic Compounds, Melting, Boiling, Triple, and Critical Point Temperatures of the Elements Estimated accuracy for Tc and Pc is indicated by the number of digits.
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+.

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 3 → 3 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] FeCl 3 ⋅ 6H 2 O → FeOCl + 5 H 2 O + 2 HCl
Ferric oxalate, also known as iron(III) oxalate, refers to inorganic compounds with the formula Fe 2 (C 2 O 4) 3 (H 2 O) x but could also refer to salts of [Fe(C 2 O 4) 3] 3-. Fe 2 (C 2 O 4 ) 3 (H 2 O) x are coordination polymers with varying degrees of hydration.
Iron(III) oxide in a vial. Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3. It occurs in nature as the mineral hematite, which serves as the primary source of iron for the steel industry. It is also known as red iron oxide, especially when used in pigments.
