Hydrated niobium peroxide, Nb 2 O 7 · 4 H 2 O having niobium: peroxy oxygen as 1:1, is prepared. The peroxy oxygen is lost at room temperature slowly and continuously. The differential thermal analysis gives an exothermic peak at 190°C due to the disruption of the peroxy group. The infrared spectrum of the peroxide indicates polymeric nature of niobium peroxide and coordinated peroxide, water and hydroxyl groups. A triangular ring structure is suggested for the peroxy niobium group. Niobium hydroxide has also been studied under similar conditions to serve as a reference.
