Preparation

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

Praseodymium perchlorate can form two complexes with crown ether 18-crown-6 in stoichiometric 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]
