Neodymium perrhenate is an inorganic compound with the chemical formula Nd(ReO₄)₃, which exists in anhydrous and tetrahydrate.Varfolomeev, M. B.; Plyushchev, V. E.; Rybakov, K. A.

It can be obtained by reacting excess neodymium oxide with 240 g/L perrhenic acid solution.Plyushchev, V. E.; Amosov, V. M.; Varfolomeev, M. B.

In its solution, NdReO₄²⁺ and Nd(ReO₄)²⁺ can be observed with stability constants of 16.5 and 23.6, respectively.Petrov, K. I.; Orlin, N. A.; Plyushchev, V. E.
