Chemical compound

Praseodymium(III) perchlorate is the perchlorate salt of praseodymium, with the chemical formula of Pr(ClO₄)₃.^[3]

Preparation[edit]

Praseodymium(III) perchlorate can be prepared from praseodymium(III,IV) oxide.^[4][5] Dissolving praseodymium(III,IV) oxide in a slight excess of hydrochloric acid and adding a small amount of hydrogen peroxide can prepare praseodymium perchlorate.^[5]

Chemical properties[edit]

Praseodymium perchlorate can form two complexes with crown ether 18-crown-6instoichiometric ratios of 1:1 and 1:2.,^[6] and can form complexes with L-proline,^[7] glutamic acid,^[4] mandelic acid,^[4] penicillamine.^[4] It can also form complexes with imidazole and alanine.^[5]
