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.
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 iron compounds produced on the largest scale in industry are iron(II) sulfate (FeSO 4 ·7H 2 O) and iron(III) chloride (FeCl 3). The former is one of the most readily available sources of iron(II), but is less stable to aerial oxidation than Mohr's salt ( (NH 4 ) 2 Fe(SO 4 ) 2 ·6H 2 O ).
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+.
