Properties

Physical properties

Neodymium(III) perchlorate forms pale purple crystals when in its anhydrous form. It is soluble in water. It forms crystals Nd(ClO₄)₃·''n'' H₂O, where ''n'' = 4, 4.5 are purple-pink crystals, ''and n'' = 6 forms pale pink to lavender crystals.

Alkaline salts

Nd(ClO₄)₃ can form alkaline salts, with the general formula of Nd(OH)_x(ClO₄)_{3 − x}. The salt with x = 1.5 (saturated with 5 water atoms) is a light purple crystal with d = 2.88 g/cm³.
