Samarium(III) perchlorate is an inorganic compound with the chemical formula Sm(ClO4)3.
Samarium(III) perchlorate can be obtained by the reaction of perchloric acid and samarium(III) oxide.[3] The hydrate precipitated from the solution can be dehydrated with dichlorine hexoxide to obtain the anhydrous form.[1]
Anhydrous samarium perchlorate forms hexagonal crystals, space group P63/m, unit cell parameters a=9.259 Å, c=5.746 Å, Z=2.[4] It reacts with ammonium thiocyanate and 1-butyl-3-methylimidazolium thiocyanate ([BMIM]SCN) in absolute ethanol to obtain the ionic liquid [BMIM]4[Sm(NCS)7(H2O)].[5]
