Materials Data on ZrO2 by Materials Project

ZrO2 crystallizes in the tetragonal P4_2/nmc space group. The structure is three-dimensional. Zr4+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.09 Å) and four longer (2.44 Å) Zr–O bond lengths. O2- is bonded to four equivalent Zr4+ atoms to form a mixture of distorted edge and corner-sharing OZr4 tetrahedra.
