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

Contents

Preparation

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]

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. [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]

Titanium perchlorate is a molecular compound of titanium and perchlorate groups with formula Ti(ClO4)4. Anhydrous titanium perchlorate decomposes explosively at 130 °C and melts at 85 °C with a slight decomposition. It can sublime in a vacuum as low as 70 °C, and can form vapour at up to 120°. Titanium perchlorate is quite volatile. It has density 2.35. It decomposes to TiO2, ClO2 and dioxygen O2 Also TiO(ClO4)2 is formed during decomposition.

Zirconium perchlorate is a molecular substance containing zirconium and perchlorate groups with formula Zr(ClO4)4. Zr(ClO4)4 is a volatile crystalline product. It can be formed by reacting zirconium tetrachloride with dry perchloric acid at liquid nitrogen temperatures. Zr(ClO4)4 sublimes slowly in a vacuum at 70°C showing that the molecule is covalently bound rather than being ionic. The reaction also forms some zirconyl perchlorate (or zirconium oxyperchlorate) ZrO(ClO4)2 as even apparently pure perchloric acid is in equilibrium with dichlorine heptoxide, hydronium ions and perchlorate ions. This side product can be minimised by adding more dichlorine heptoxide or doing the reaction as cold as possible.
