Scandium(III) chloride is the inorganic compound with the formula ScCl 3. It is a white, high-melting ionic compound, which is deliquescent and highly water-soluble. [2] This salt is mainly of interest in the research laboratory. Both the anhydrous form and hexahydrate (ScCl 3 •6H 2 O) are commercially available.
In all four halides, the scandium is 6-coordinated. They can be prepared by reacting scandium oxide or scandium hydroxide with the corresponding acid: [3] Sc(OH) 3 + 3 HX → ScX 3 + 3 H 2 O. The halides are Lewis acids; for example, ScF 3 dissolves in a solution containing excess fluoride ion to form [ScF 6] 3−. The coordination number 6 is ...
Scandium is only the 50th most common element on Earth (35th most abundant element in the crust), but it is the 23rd most common element in the Sun [17] and the 26th most abundant element in the stars. [18] However, scandium is distributed sparsely and occurs in trace amounts in many minerals. [19]

Scandium is distributed sparsely and occurs in trace amounts in many minerals. [69] Rare minerals from Scandinavia [70] and Madagascar [71] such as gadolinite, euxenite, and thortveitite are the only known concentrated sources of this element, the latter containing up to 45% of scandium in the form of scandium(III) oxide. [70]
Scandium(III) oxide or scandia is a inorganic compound with formula Sc 2 O 3.It is one of several oxides of rare earth elements with a high melting point.It is used in the preparation of other scandium compounds as well as in high-temperature systems (for its resistance to heat and thermal shock), electronic ceramics, and glass composition (as a helper material).
Scandocene is an organoscandium compound with the chemical formula Sc(C 5 H 5) 3.It is a straw-colored crystal and can be obtained by reacting anhydrous scandium(III) chloride and sodium cyclopentadienide in tetrahydrofuran. [1]
Scandium(III) hydroxide is an inorganic compound with the chemical formula Sc(OH) 3, the trivalent hydroxide of scandium. It is an amphoteric compound. [2] It is slightly soluble in water, and its saturated solution (pH = 7.85) contains Sc(OH) 3 and a small amount of Sc(OH) + 2. The solubility of scandium(III) hydroxide in water is 0.0279 mol/L.
