PaO2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. Pa(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. O(1) is bonded to four equivalent Pa(1) atoms to form a mixture of corner and edge-sharing OPa4 tetrahedra.
PaO2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. Pa(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. All Pa(1)-O(1) bond lengths are 2.35 Å. O(1) is bonded to four equivalent Pa(1) atoms to form a mixture of corner and edge-sharing OPa4 tetrahedra.
