CaO2 is Fluorite-like structured and crystallizes in the monoclinic C2/c space group. Ca(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ca(1) atoms to form a mixture of corner and edge-sharing OCa4 tetrahedra. In the second O site, O(2) is bonded to four equivalent Ca(1) atoms to form a mixture of corner and edge-sharing OCa4 tetrahedra.
CaO2 is Fluorite-like structured and crystallizes in the monoclinic C2/c space group. Ca(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. There are a spread of Ca(1)-O(1) bond distances ranging from 2.41-2.47 Å. There are a spread of Ca(1)-O(2) bond distances ranging from 2.39-2.44 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ca(1) atoms to form a mixture of corner and edge-sharing OCa4 tetrahedra. In the second O site, O(2) is bonded to four equivalent Ca(1) atoms to form a mixture of corner and edge-sharing OCa4 tetrahedra.
