Get QuoteZrO2 is Baddeleyite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Zr4+ is bonded to seven O2- atoms to form a mixture of distorted corner and edge-sharing ZrO7 pentagonal bipyramids. There are a spread of Zr–O bond distances ranging from 2.07–2.31 Å. There are two inequivalent O2- sites.
