HfO2 is Baddeleyite structured and crystallizes in the monoclinic P2_1/c space group. Hf(1) is bonded to three equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing HfO7 pentagonal bipyramids. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Hf(1) atoms. In the second O site, O(1) is bonded to four equivalent Hf(1) atoms to form a mixture of corner and edge-sharing OHf4 tetrahedra.

Hf(1) is bonded to three equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing HfO7 pentagonal bipyramids. There are a spread of Hf(1)-O(2) bond distances ranging from 2.03-2.13 Å. There are a spread of Hf(1)-O(1) bond distances ranging from 2.13-2.24 Å. There are two inequivalent O sites.
