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.
ZrO2 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.
ZrO₂ is Fluorite structured and crystallizes in the cubic Fm̅3m space group. Zr⁴⁺ is bonded in a body-centered cubic geometry to eight equivalent O²⁻ atoms. All Zr-O bond lengths are 2.20 Å. O²⁻ is bonded to four equivalent Zr⁴⁺ atoms to form a mixture of edge and corner-sharing OZr₄ tetrahedra.
ZrO2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to six O2- atoms to form a mixture of distorted corner and edge-sharing ZrO6 octahedra.
