Chemical compound

Samarium(III) perchlorate is an inorganic compound with the chemical formula Sm(ClO₄)₃.

Preparation

Samarium(III) perchlorate can be obtained by the reaction of perchloric acid and samarium(III) oxide. The hydrate precipitated from the solution can be dehydrated with dichlorine hexoxide to obtain the anhydrous form.

Properties

Anhydrous samarium(III) perchlorate forms hexagonal crystals, space group P63/m, unit cell parameters a=9.259 Å, c=5.746 Å, Z=2. It reacts with ammonium thiocyanate and 1-butyl-3-methylimidazolium thiocyanate (SCN) in absolute ethanol to obtain the ionic liquid ₄.
