Neodymium(III) perchlorate is an inorganic compound. It is a salt of neodymium and perchloric acid with the chemical formula of Nd(ClO<sub>4</sub>)<sub>3</sub>. It is soluble in water, forming purple-pink, hydrated crystals.
Neodymium(III) perchlorate forms pale purple crystals when in its anhydrous form.
It is soluble in water, forming a fluorescent solution.
It forms crystals Nd(ClO<sub>4</sub>)<sub>3</sub>÷nH<sub>2</sub>O, where n = 4, 4.5 are purple-pink crystals, and n = 6 forms pale pink to lavender crystals.
Nd(ClO<sub>4</sub>)<sub>3</sub> can form alkaline salts, with the general formula of Nd(OH)<sub>x</sub>(ClO<sub>4</sub>)<sub>3 â x</sub>. The salt with x = 1.5 (saturated with 5 water atoms) is a light purple crystal with d = 2.88 g/cmó.
Nd(ClO<sub>4</sub>)<sub>3</sub> can form compounds with hydrazine, such as Nd(ClO<sub>4</sub>)<sub>3</sub>÷6N<sub>2</sub>H<sub>4</sub>÷4H<sub>2</sub>O which is a small white crystal that is soluble in water, methanol, ethanol and acetone, and insoluble in toluene, with density of 2,3271 g/cmó at 20 ðC.
